TPS53124 Buck Controller Evaluation Module User's Guide 1

1 Description

The TPS53124 is a dual, adaptive on-time D-CAP™ mode synchronous buck controller. The TPS53124 enables

system designers to cost-effectively complete the suite of DTV POL regulators and digital STB regulators with a

low external component count. The main control loop for the TPS53124 uses the D-CAP mode that is optimized

for low-ESR output capacitors such as POSCAP, SP-CAP, or high polymer chemistry and provides fast transient

response with no external compensation. The TPS53124 provides conversion voltages (drain voltage for the

synchronous high-side MOSFET) from 4.5 V to 24 V and output voltages from 0.76 V to 5.5 V.

The HPA332 (TPS53124EVM) evaluation module is a high-efficiency, dual synchronous buck converter providing

1.05 V at 4 A and 1.8 V at 4 A from 5-V to 22-V input. This user's guide describes the HPA332 performance.

4.2 Test Procedure

1. Make sure the switches SW1 (EN1) and SW2 (EN2) are in OFF position.

2. Apply appropriate VIN voltage to VIN and VIN_GND terminals.

3. Turn on SW1 (EN1), CH1-output will start up.

4. Turn on SW2 (EN2), CH2-output will start up.

5 Configuration

This EVM can be set at desired configurations. Refer to the following specific setting configuration sections.

5.1 Bootstrap Diode Selection

Bootstrap diodes are not populated on this EVM since TPS53124 has them built-in. External Schottky diodes

can be added to improve efficiency.
