●The TPS54226EVM-539 is an evaluation module for TPS54226 a single, adaptive on time 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 switching frequency is internally set at a nominal 700KHz. The high side and low side switching MOSFETs are incorporated inside the TPS54226 package along with the gate drive circuitry. The low drain to source on resistance of the MOSFETs allow the TPS54226 to achieve high efficiencies and helps keep the junction temperature low at high output currents. The TPS54226 also has an auto skip mode to enable higher efficiency at light loads. The TPS54226 is designed to provide up to a 2A output from an input control voltage source of 4.5V to 18V and an input power voltage source of 2V to 18V. The output voltage range is from 0.76V to 5.5V.
