LMZM33602/03 Step-Down DC/DC Power Modules

LMZM33602/03 Step-Down DC/DC Power Modules

Texas Instruments' LMZM33602 and LMZM33603 power module are easy-to-use integrated power solutions that combine a 2 A/3 A, step-down, DC/DC converter with power MOSFETs, a shielded inductor, and passives into a low-profile package. This power solution requires as few as four external components and eliminates the loop compensation and magnetics part selection from the design process.

The 9 mm x 7 mm x 4 mm 18-pin QFN package is easy to solder onto a printed circuit board and allows a compact, low-profile, point-of-load design. The full feature set, including power good, programmable UVLO, pre-bias start-up, and overcurrent and over-temperature protection, make the LMZM33603 an excellent device for powering a wide range of applications.
