Texas Instruments' LMZM33602RLRR 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.<strong>Features:</strong> Complete integrated power solution As few as four external components, Minimum solution size < 100 mm2, 9 mm x 7 mm x 4 mm QFN package All pins accessible from package perimeter , Pin compatible with 3 A LMZM33603 (LMZM33602), Pin compatible with 2 A LMZM33602RLRR (LMZM33603), Output voltage range: 1 V to 18 V (LMZM33602), 1 V to 13.5 V at 3 A (LMZM33603), 1 V to 18 V at 2 A (LMZM33603), Input voltage range: 4 V to 36 V, Efficiencies up to 95%, Adjustable switching frequency (200 kHz to 1.2 MHz), Allows synchronization to an external clock, Power-good output, Meets EN55011 Class B radiated EMI standards, Operating IC junction range: -40°C to +125°C, Operating ambient range: -40°C to +105°C, Create a custom design using the LMZM33602RLRR with the WEBENCH® Power Designer and the LMZM33603 with the WEBENCH® Power Designer, Factory and building automation, Smart grid and energy, Industrial, Medical, Defense, Inverted output applications
