Description

The LMZM33604 power module is an easy-to-use integrated power solution that combines a4-A DC/DC converter with power MOSFETs, a shielded inductor, and passives in a low-profile package.This power solution requires as few as four external components and eliminates the loopcompensation and inductor part selection from the design process.

The 16 mm × 10 mm × 4 mm, 41-pin, QFN package is easy to solder onto a printed circuitboard and allows for a compact, low-profile point-of-load design. The LMZM33604 feature setincludes power good, adjustable soft start, tracking, synchronization, programmable UVLO, prebiasstart-up, selectable auto or FPWM modes, as well as overcurrent and overtemperature protection. TheLMZM33604 can be configured as negative output voltage for inverting applications.
