The TPS54225EVM-538 is an evaluation module for TPS54225 Synchronous Step Down DCAP2 mode converter. The evaluation module is a single synchronous buck converter providing 1.05V at 2A from 5V to 17V input. The TPS54225 is a single, adaptive on time DCAP2 mode synchronous buck converter requiring a very low external component count. The DCAP2 control circuit is optimised for low ESR output capacitors such as POSCAP, SP CAP. The switching frequency is internally set at a nominal 700KHz. The high side and low side switching MOSFETs are incorporated inside the TPS54225 package along with the gate drive circuitry. The low drain to source on resistance of the MOSFETs allow the TPS54225 to achieve high efficiencies and helps keep the junction temperature low at high output currents. The output voltage range is from 0.76V to 5.5V.
