2 Introduction
The Texas Instruments LP8862-Q1EVM evaluation module (EVM) helps designers to evaluate the
operation and performance of the LP8862-Q1 device. The LP8862-Q1EVM uses the LP8862-Q1 to drive
up to 2 LED strings for LCD backlighting with high efficiency. Information about output voltage and current
ratings of the LP8862-Q1 can also be found in the device data sheet (SNVSA75).
Power supply connection for the VIN and test points for each signal can be found on the evaluation board.
A separate LED board can be used as a load; it is also possible to connect LCD panel to the output
connectors.
For evaluation purposes, the EVM has been tested over a 4.5-V to 40-V input range. This voltage range is
within the recommended operating range for input voltage of the LP8862-Q1. Users are cautioned to
evaluate their specific operating conditions and choose components with the appropriate voltage ratings
before designing this circuitry into a final product.

3 Description of the LP8862-Q1
The LP8862-Q1 is an automotive high-efficiency LED driver with integrated boost/SEPIC converter. It has
2 high-precision current sinks that can be controlled by a PWM input signal.
The boost converter has adaptive output voltage control based on the LED current sink headroom
voltages. This feature minimizes the power consumption by adjusting the voltage to lowest sufficient level
in all conditions. Boost controller supports spread spectrum for switching frequency and an external
synchronization with dedicated pin. The high switching frequency allows the LP8862-Q1 to avoid
disturbance for AM radio band.
The LP8862-Q1 can drive an external p-FET to disconnect the input supply from the system in the event
of a fault, reduce inrush current and standby power consumption.
The input voltage range for LP8862-Q1 is from 4.5 V to 40 V to support automotive stop/start and load
dump condition. LP8862-Q1 supports PWM brightness dimming ratio up to 10 000:1 for input PWM
frequency of 200 Hz. The LP8862-Q1 integrates extensive safety and protection features.

Start-Up of the EVM and Power Sequences www.ti.com
6 Start-Up of the EVM and Power Sequences
The LP8862-Q1 EVM is set up for easy start-up:
• Connect LEDs to OUT1 and OUT2 of connector J16. (Note: LED current default is 160 mA and boost
voltage default is 37 V. LED outputs that are not used must be grounded via jumpers J11 orJ12.)
• Connect input (BATTERY) voltage 12V to connector J25.
The LEDs turn on immediately because the jumpers on the EVM are set up for PWM input of 100% duty
cycle. For connector and jumper positions, see Figure 1 and Figure 9.
Input (BATTERY) voltage range is 4.5 V to 40 V.
The LP8862-Q1 has a dual function VDDIO/EN pin. By default, VDDIO/EN = 3.3V is generated
automatically on the EVM from battery input voltage, via jumpers J1 and J26. VDDIO/EN acts as enable
for the chip as well as supply/reference voltage for IO logic. Device starts when VIN voltage is present and
above the VIN UVLO voltage level (4 V), and the VDDIO/EN voltage is set above threshold voltage (1.2 V).
By default, boost switching frequency is 400 kHz (jumper J4 connecting R3 = 160 kΩto FSET) and boost
maximum voltage is 37 V (R12 = 750 kΩand R13 = 130 kΩ). See Section 7.1 and Section 7.3 for
descriptions of how to change boost settings.
By default, LED current is 160 mA per string (jumper J5 connecting R4= 30 kΩto ISET). See Section 8.2
for descriptions of how to change LED current setting.
Alternatively to internal LDO, device circuitry can be powered from external power supply (4.4...5.25 V)
connected to LDO pin. The internal LDO is disabled in this case.
6.1 PWM input to Initiate Start-up Sequence
The backlight is started by setting PWM input high. By default, LP8862-Q1 EVM has PWM input set high
(100% duty cycle). It is connected to VDDIO through jumper J2. Alternatively, an external PWM signal can
be connected by removing jumper J2 , shorting pins 3 and 4 on jumper J17 and connecting the external
PWM to connector J18.
Figure 5. Typical Start-up Sequence
6.2 Shutdown Sequence
The backlight is shut down (LEDs turned off) by setting PWM input low or when VDDIO/EN = 0. If
VDDIO/EN is set low, the LP8862-Q1 enters low-power mode with internal LDO disabled.

7 Boost Converter
7.1 Switching Frequency
Switching frequency for boost is defined as 300 kHz to 2.2 MHz. However, frequency can be set from 250
kHz to 2.2 MHz with the external resistor connected to FSET pin, thus allowing the LP8862-Q to be
synchronized with an external frequency of 300 kHz (see details in Section 7.2).
Switching frequency is defined by resistor R3 connected to FSET pin:
ƒSW = 67600/(RFSET + 6.4)
where
• ƒSW - switching frequency, kHz
• RFSET – frequency setting resistor, kΩ(1)
Figure 6. Switching Frequency vs RFSET
By default, jumper J4 is installed on the board connecting R3 = 160 kΩto FSET pin which sets the boost
at 400 kHz. An external resistor can be connected to change the switching frequency: remove jumper J4,
short pins 7 and 8 on jumper J17, and connect the external resistor to connector J18. Boost internal
parameters will be adjusted automatically according to chosen frequency.
7.2 Spread Spectrum and Synchronization
The SYNC pin is used to enable boost spread spectrum or, alternatively, to synchronize boost switching
with an external frequency. To disable spread spectrum functionality this pin should be connected to
ground and to enable spread spectrum SYNC should be connected to VDDIO/EN. Selection is done with
jumper J3. When spread spectrum is enabled, boost switching frequency is modulated ±3% from set
frequency with 1.875-kHz modulation frequency.
If an external frequency is detected at SYNC pin, the device starts to synchronize boost with this
frequency. Frequency should be higher than the switching frequency set by RFSET resistor and be in range
1.2...1.5 × ƒSW SET.

Boost Converter www.ti.com
7.3 Voltage Control
Maximum boost converter voltage is defined by the feedback voltage divider R12 and R13.
Recommended value for R13 is 130 kΩ. R12 value can be calculated with the following equation:
where
• VBG = 1.2 V
• R12, R13 values are in kΩ(2)
Figure 7. Converter Maximum Output Voltage vs R12
Maximum voltage should be chosen based on the maximum voltage required for LED strings.
Recommended maximum voltage is about 30% higher than maximum LED string voltage. Initial boost
voltage is about 88% of maximum voltage. Boost output voltage is adjusted automatically based on LED
current sink headroom voltage.
Default setting for boost maximum voltage is 37 V (R12 is 750 kΩ).
8 LED Current Sinks
8.1 Output Configuration
The LP8862-Q1 detects LED output configuration during start-up. Output connected to ground is disabled
and excluded from adaptive boost control and fault detections. Non-used LED output must be grounded,
with jumper J11 or J12.
8.2 Current Setting
Maximum current for the LED outputs is controlled with an external resistor (R4) connected to ISET pin.
Maximum current can be calculated as follows:
where
• VBG = 1.2 V
• RISET – current setting resistor (R4), kΩ
• ILED – output current per output, mA (3)

8.3 Brightness Control
The LP8862-Q1 controls the brightness of the display with conventional PWM. Output PWM will directly
follow the input PWM. Input PWM frequency can be in the range of 100 Hz to 20 kHz.
An external digital PWM signal can be connected to connector J18. For test purposes the PWM input of
LP8862-Q1 can be connected to ground to turn off LEDs or connected to VDDIO/EN to set up 100%
brightness using jumper J2.
9 Fault Detection
9.1 Fault Indicator
The LP8862-Q1 has fault detection for LED open and short, VIN input overvoltage, VIN undervoltage
lockout, power-line overcurrent, boost overcurrent, and thermal shutdown. An open-drain FAULT pin
indicates faults. The FAULT pin can be connected to LED D2 for indication (jumper J10).
