TPS54225

illustrate

The TPS54225 is a D-CAP2™ mode synchronous buck converter with adaptive turn-on time. This TPS54225 enables system designers to complete a regulated power bus kit for a wide range of end devices with a cost-effective, low-component-count, low-standby current solution. D-CAP2™ mode control for TPS54225 main control cycle provides a fast transient response without the need for external compensation elements.

The TPS54225 also features dedicated circuitry that allows the device to accommodate two low-equivalent series resistors (ESR) output capacitors, such as POSCAP or SP-CAP ceramic capacitors with ultra-low ESR. The device operates from a 4.5 V to 18-V CC input and a VIN input supply voltage from 2 V to 18 - V.
