Description

The TPS54226EVM-539 user’s guide contains background information for the TPS54226 as well as support documentation for the TPS54226EVM-539 evaluation module. Also included are the performance specifications, schematic and the bill of materials for the TPS54226EVM-539. The TPS54226 is 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 700 kHz. 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 dc/dc synchronous converter is designed to provide up to a 2-A 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.
