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.
