Texas Instruments LMZM33604/LMZM33606 Power Modules

Texas Instruments LMZM33604/LMZM33606 Power Modules are power solutions that combine a 4A (LMZM33604) or 6A (LMZM33606) 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 16mm×10mm×4mm, 41-pin, QFN package is easy to solder onto a printed circuit board and allows for a compact, low-profile point-of-load design. The LMZM33604/LMZM33606 feature sets include power good, adjustable soft start, tracking, synchronization, programmable UVLO, pre-bias start-up, selectable auto or FPWM modes, as well as overcurrent and overtemperature protection. The Texas Instruments LMZM33604/LMZM33606 can be configured as negative output voltage for inverting applications.
