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.
