Texas Instruments LMZM33602/LMZM33603 Power Module

Texas Instruments LMZM33602/LMZM33603 Power Module is an easy-to-use integrated power solution that combines a 2A (LMZM33602) or 3A (LMZM33603), 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 9mm×7mm×4mm 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 Texas Instruments LMZM33602/LMZM33603 an excellent device for powering a wide range of applications.
