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.
