Texas Instruments TPS55340 | Demoboard PM20550

Description

The PMP20550 is a simple design using a SEPIC to produce 3 power rails in which 2 of those are isolated from the input supply. This design is made entirely with automotive qualified IC's and magnetics. The PMP20550 reference design has been designed with optional components to allow the user to adjust output voltage precision as desired.
