The TPSM846C24 is a 35-A, fixed-frequency, step-down power module. The module incorporates the controller, power MOSFETs, inductor, and associated components into a rugged, thermally enhanced, surface-mount package. The user supplies the input and output capacitors along with a few other passive components to set the operating parameters of the module. Two modules can be configured to work in parallel to provide up to a 70-A, two-phase power solution.

The 15 mm × 16 mm component footprint is easy to solder onto a printed circuit board and allows a compact, point-of-load design.
