3 Description

The LMZM33606 power module is an easy-to-use

integrated power solution that combines a 6-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 loop compensation 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 circuit board and

allows a compact, low-profile point-of-load design.

The LMZM33606 feature set includes power good,

adjustable soft start, tracking, synchronization,

programmable UVLO, prebias start-up, selectable

auto or FPWM modes, as well as over-current and

over-temperature protection. The LMZM33606 can be

configured as negative output voltage for inverting

applications.
