4V to 17V, current mode, quad 6A stackable step-down power module

The TPSM8F7x20 is a power-dense quad-channel buck power module designed to provide

efficient and reliable power conversion for a wide output voltage range from 0.6V to 11V.

The module integrates MOSFETs, inductor, and select capacitors to reduce board space and

layout complexity. The module can be configured into both multiphase and multi-output rails

by supporting 2, 3, and 4-phase stackability with interleaved phases. Under

steady-state conditions the module operates in FCCM with a fixed-frequency that is resistor

adjustable from 400kHz to 2.2MHz and synchronizable to an external clock.

TPSM8F7x20 module

employs current mode control with internal and external compensation. Sequencing

requirements are easily met with the external soft-start, active output discharge,

adjustable EN, and power-good features. A full suite of protection features (output OV and

UV, input UVLO, TSD, OC) are also included for robustness.
