RTKA211650DE0000BU Evaluation Board Manual
1. Functional Description
The RTKA211650DE0000BU provides a comprehensive and versatile platform for you to evaluate functionality
and prototype an application of the integrated 60V, 5A synchronous buck regulator RAA211650. This evaluation
board includes the options to evaluate most of the features of RAA211650. Either a toggle switch, jumper or 0Ω
jumper resistors have been used to evaluate the features.
1.1 Operating Range
The RTKA211650DE0000BU evaluation board evaluates RAA211650 with PVIN from 4.5V to 60V and continuous
load of 5A. For proper functioning of the evaluation board, Renesas recommends operating the board within the
specifications.
The inductance and capacitance value of the regulator is chosen for 3.3V VOUT and 500kHz switching frequency.
You can replace these components with different values if a different operating condition is required.
Also, you can change the EBIAS to an external source(<12V), soft-start time, start-up delay, compensation,
switching frequency, enable spread spectrum, or synchronize to external clock. See the RAA211650 datasheet
and design spreadsheet to calculate the components for a required setting.
Updates on the output inductor, capacitors, and R9 may be required with changes on the operating VOUT, load,
and switching frequency.
1.2 Recommended Equipment
▪Power supply that can deliver 5V or higher with at least 5A source current capability
▪Electronic load capable of sinking at least 5A current
▪4-channel oscilloscope with voltage and current probes
1.3 Quick Start Guide
Use the following Quick Setup Guide to configure and power-up the board for proper operation.
1. Set the power supply voltage to 12V and turn off the power supply. Connect the positive output of the power
supply to J1 (PVIN) and the negative output to J2 (GND).
2. Connect an electronic load to J5 (VOUT) for the positive connection and J4 (GND) for the negative connection.
3. Place scope probes to VOUT (J3), PHASE (J6), and/or other test points of interest.
4. Toggle the selection switch SW1 to ON position.
5. Set the load current to 0.1A and turn on the power supply. The output voltage should be in regulation with
nominal 3.3V output.
6. Slowly increase the load up to 5A. The output voltage should remain in regulation with nominal 3.3V output.
7. Slowly sweep PVIN from 4.5V to 60V. The output voltage should remain in regulation with nominal 3.3V output.
8. Decrease the input voltage to 0V to shut down the regulator.

1.4 Connectors, Test Points, Selection Switches, and Jumper Descriptions
The RTKA211650DE0000BU evaluation board includes I/O connectors, test points, selection switch, and jumpers
to provide a comprehensive and versatile platform for evaluation of RAA211650.Table 1 shows the description of
them.
1.4.1 Enable
Switch SW1 enables and disables RAA211650. SW1 in position ON ties EN to PVIN through R1,R2 divider on
PVIN. The EN threshold can be changed by changing the values of R1 and R2. With SW1 in OFF position, EN
can be driven by external source as well.
1.4.2 Soft-Start
The RTKA211650DE0000BU is set for an internal soft-start of 2ms. To change the soft-start time, remove R10 and
update C6 to get the required soft-start time using Equation 1.
where tss is the soft-start time in milliseconds.
1.4.3 Delay
The RTKA211650DE0000BU is set for start-up delay of 2ms. To change the delay time, change C8 using
Equation 2.
where tDELAY is the delay time in milliseconds.
Note: If no delay is required, mount 0Ωresistor for R14.

1.4.4 Switching Frequency
The RTKA211650DE0000BU is set for an internal default switching frequency of 500kHz. To change the switching
frequency, remove R7 and mount R6 using equation 3.
1.4.5 Compensation
The RTKA211650DE0000BU is set for internal compensation. To change to external compensation, remove R12
and update R15, C9, and C7. Verify the compensation using the design spreadsheet.
1.4.6 Spread Spectrum
To disable the spread spectrum, use a 0Ωresistor for R5 or short the jumper J7. To enable the spread spectrum,
use a 0Ωresistor for R4, keep jumper J7 open, and do not put a resistor on R5.
1.4.7 EXT CLK Synchronization
The RAA211650 can be synchronized to an external clock by connecting it to J7. The external clock signal is
divided internally to half and PWM clock synchronizes only if the divided external clock frequency is greater than
110% of the frequency set by RT. The external clock should meet the specifications described in the RAA211650
datasheet.
1.4.8 3.3V VOUT with Internal Feedback
The RAA211650 has an internal feedback for a 3.3V VOUT setting. To use this feature, remove R22, C20, R23,
and R21, and use a 0Ωresistor for R24.
1.4.9 Other Output Voltages
RTKA211650DE0000BU is set for 3.3V VOUT using R21 and R23. Other output voltages are programmable by
updating the values for these resistors. Renesas recommends keeping R21 as 20kΩand change the value for
R23 using Equation 4.
With the change on VOUT, update the output inductor, capacitors, and R9 using the design spreadsheet.
1.4.10 EBIAS
EBIAS improves efficiency for the internal bias supply. The default setting on the board uses VOUT as source of
EBIAS. Limit the EBIAS source to 12V. If VOUT is more than 12V, remove R19 and an external EBIAS source
(within EBIAS specification) can be used by connecting the source to EBIAS and GND_3 test points. If EBIAS is
not used, remove R19 and install a 0Ωresistor for R20.

2.1 Layout Guidelines
The printed circuit board (PCB) layout is critical for proper operation of the RAA211650. The following guidelines
are recommended to achieve good performance.
1. Use multilayer PCB structure to achieve optimized performance. Renesas recommends using a four layer PCB
with 2oz copper on outer and 1oz copper in inner layers.
2. Use the combination of a bulk capacitor and smaller ceramic capacitors with low ESL for input capacitors and
place them as close as possible to the IC. Place the ceramic input capacitor on the same PCB surface layer.
3. Place the ceramic AVCC capacitor on the same PCB surface layer as the regulator and as close as possible
to the AVCC and AGND pins. Use a 1µF ceramic capacitor for AVCC and use 1Ωresistor to connect AVCC to
PVCC.
4. Place the ceramic PVCC capacitor on the same PCB surface layer as the regulator and as close as possible
to the PVCC and PGND pins.
5. Add plenty of thermal vias under the exposed pad of the regulator for better heat dissipation. Connect the vias
to GND planes underneath.
6. Route the output voltage feedback signal away from BOOST and PHASE. Place feedback resistors close to
FB pin of the regulator.
7. Place bootstrap capacitor close to the IC between BOOT and PHASE pins on same PCB layer as the regulator.
Renesas recommends using a 0.1µF ceramic capacitor.
8. The copper area of the PHASE NODE should not be more than needed. Place the inductor close to regulator.
9. Place an output capacitor close to the inductor.
10. Keep SET resistor close to the SET pin. Avoid running other analog signals close to the SET pin or SET resistor.
