Product Overview

The TPS54227EVM-686 is an Evaluation Module for TPS54227, a single, adaptive on time, D-CAP2 mode, synchronous buck converter requiring a 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 switching frequency is internally set at a nominal 700KHz. The high side and low side switching MOSFETs are incorporated inside the TPS54227 package along with the gate drive circuitry. The low drain to source on resistance of the MOSFETs allows the TPS54227 to achieve high efficiencies and helps keep the junction temperature low at high output currents. The TPS54227 dc/dc synchronous converter is designed to provide up to a 2A output from an input voltage source of 4.5V to 18V. The output voltage range is from 0.76V to 7V.
