2 Introduction
The Texas Instruments TPS61194xEVM evaluation module (EVM) helps designers to evaluate the
operation and performance of the TPS61194 or TPS61194-Q1 device. The TPS61194xEVM uses the
TPS61194 or TPS61194-Q1 to drive up to 4 LED strings for LCD backlighting with high efficiency.
Information about output voltage and current ratings of the TPS61194 or TPS61194-Q1 can also be found
in the device data sheets (SNVSAF5 and SNVSAE9).
A 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 EVMs have 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 TPS61194 or TPS61194-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 TPS61194 or TPS61194-Q1 Device
The TPS61194 or TPS61194-Q1 is an automotive high-efficiency LED driver with integrated boost/SEPIC
converter. It has 4 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 a dedicated pin. The high switching frequency allows the TPS61194 or TPS61194-
Q1 to avoid disturbance for AM radio band.

6 Start-Up of the EVM and Power Sequences
The TPS61194xEVM is set up for easy start-up:
• Connect LEDs to OUT1 - OUT4 of connector J16. (Note: LED current default is 100 mA, and maximum
boost voltage default is 37 V. LED outputs that are not used must be grounded via jumpers J11 to
J14.)
• Connect input (BATTERY) voltage 12 V 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 8.
Input (BATTERY) voltage range is 4.5 V to 40 V.
The TPS61194 or TPS61194-Q1 has a dual function VDDIO/EN pin. By default, VDDIO/EN = 3.3 V is
generated automatically on the EVM from battery input voltage via jumpers J1 and J26. VDDIO/EN acts
as enable for the device as well as supply/reference voltage for IO logic. The 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
description on how to change boost settings.
By default, LED current is 100 mA per string (jumper J5 connecting R4 = 24 kΩto ISET). See Section 8.2
for the description on how to change LED current setting.
Alternatively to internal LDO, device circuitry can be powered from external power supply (4.4 V to 5.25 V)
connected to the LDO pin. Internal LDO are disabled in this case.
6.1 PWM Input to Initiate Start-up Sequence
The backlight is started by setting PWM input high. By default, the TPS61194xEVM has PWM input set
high (100% duty cycle), which 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.
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 TPS61194 or TPS61194-Q1 enters low-power mode with internal LDO disabled.

7.1 Switching Frequency
Switching frequency for boost is defined as 300 kHz to 2.2 MHz. However, frequency from 250 kHz to 2.2
MHz can be set by the external resistor connected to the FSET pin, thus allowing the device to be
synchronized with the lowest 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 5. Switching Frequency vs RFSET
By default, jumper J4 is installed on the board connecting R3 = 160 kΩto the 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 are adjusted automatically according to chosen frequency during start-up.
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; 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 TPS61194 or TPS61194-Q1 starts to synchronize
boost with this frequency. Frequency must be higher than the switching frequency set by RFSET resistor
and be in range 1.2 V to 1.5 V × ƒSW SET.

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 6. 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).

8.1 Output Configuration
The TPS61194 or TPS61194-Q1 detects LED output configuration during start-up. Any output connected
to ground is disabled and excluded from adaptive boost control and fault detections. Non-used LED
outputs must be grounded with jumpers J11 through J14.
8.2 Current Setting
Maximum current for the LED outputs is controlled with an external resistor (R4) connected to the 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)
Figure 7. Output Current vs RISET
8.3 Brightness Control
The TPS61194 or TPS61194-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
the TPS61194 or TPS61194-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 TPS61194 or TPS61194-Q1 has fault detection for LED open and short, VIN input overvoltage, VIN
undervoltage lockout, boost overcurrent, and thermal shutdown. Open-drain FAULT pin indicates faults.
Fault pin can be connected to LED D2 for indication (jumper J10).
