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.
