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.

The TPSM863252 operates in Eco-mode, which maintains high efficiency during light loading. The TPSM863257 operates in FCCM mode, which keeps the same frequency and lower output ripple during all load conditions. TPSM863253 is a fixed 3.3V output voltage part with FCCM mode. TPS863253 integrated divider resistors and a feedforward cap in internal module. The device integrates complete protection through OVP, OCP, UVLO, OTP, and UVP with hiccup.

The device is available in a QFN package. The junction temperature is specified from –40°C to 125°C.
