Texas Instruments TPSM863252RDX | Demoboard PMP41081E2

Description

The TPSM86325x is a simple, easy-to-use, high efficiency, high-power density, synchronous buck module with input voltage ranging from 3V to 17V and supports up to 3A continuous current.The TPSM86325x employs D-CAP3 control mode to provide a fast transient response and to support low-ESR output capacitors with no requirement for external compensation. The device can support up to 95% duty cycle operation.
