3 Description

The TPSM8A28 and TPSM8A29 buck power modules

are small and highly efficient. This module family

contains integrates inductor and basic passives, and

does not require external compensation, minimizing

solution size.

Features include differential remote sense, highperformance

integrated MOSFETs, and an accurate

0.6-V reference, D-CAP3™ control mode,selectable

Skip-mode and programmable soft-start.

TPSM8A28 and TPSM8A29 are lead-free, and fully

RoHS compliant without exemption.
