Texas Instruments  TPS565201EVM-858

The TPS565201 is a single, adaptive on-time, Eco-mode™, D-CAP2™ mode, synchronous buck converter requiring a very low external component count. The D-CAP2 control circuit is optimized for low-ESR output capacitors such as POSCAP, SP-CAP, or ceramic types and features fast transient response with no external compensation. The high-side and low-side switching MOSFETs are incorporated inside the TPS565201 package along with the gate-drive circuitry. The low drain-to-source on resistance of the MOSFETs allows the TPS565201 to achieve high efficiencies and helps keep the junction temperature low at high output currents. The TPS565201 dc/dc synchronous converter is designed to provide up to a 5-A output from an input voltage source of 4.5 V to 17 V. The output voltage range is from 0.8 V to 6.5 V. The TPS565201EVM-858 evaluation module (EVM) is a single, synchronous buck converter providing 1.05 V at 5 A from 4.5-V to 17-V input. Thie EVM user’s guide describes the TPS565201EVM-858 performance.
