Texas Instruments TPSM86325x 3A Synchronous Buck Modules

Texas Instruments TPSM86325x 3A Synchronous Buck Modules are simple, easy-to-use, high-efficiency, high-power density synchronous buck module. This device has an input voltage ranging from 3V to 17V and supports up to 3A continuous current. The TPSM86325x employs the D-CAP3 control mode to provide a fast transient response and support low-ESR output capacitors without external compensation. The device can support up to 95% of duty cycle operation.

The Texas Instruments 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. 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.
