TIDA-00783: 1.8V @ 1A, 1.2V @ 1A, 3.3V @ 0.9A, 4.5 ~ 40V in

Summary

The TIDA-00783 reference design is a triple output wide Vin power module reference design. It provides three output voltages: 3.3V, 1.8V and 1.2V, and total 6W power, and has a wide input range of 4.5V to 40V. The reference design features the LMZ36002 wide Vin power module and LMZ20502 nano module from SIMPLE SWITCHER®.

The layout is optimized for space constrained application, and the total solution size is about 400 mm2.
