The TPSM86125x 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 1A continuous current.

The TPSM86125x 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 TPSM861252 operates in Eco-mode, which maintains high efficiency during light load. The TPSM861257 operates in FCCM mode, which keeps the same frequency and lower output ripple during all load conditions. TPSM861253 is a fixed 3.3V output voltage part with FCCM mode. The device also integrates the divider resistors and a feedforward capacitor inside the module. The TPSM86125x integrates complete protection including OVP, OCP, UVLO, OTP, and UVP with hiccup.

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