TPSM846C24 Power Module

Texas Instruments' TPSM846C24 is a 4.5 V to 15 V input, 0.5 V to 2 V output, 35 A power module

Image of Texas Instruments' TPSM846C24 Power ModuleTexas Instruments' TPSM846C24 is a 35 A, fixed-frequency, step-down power module. This module incorporates a controller, power MOSFETs, an 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.
