200W Adjustable Output Dual Port USB Type-C™ Charger Reference Design
Description
This reference design is a dual port 200W synchronous buck-boost utilizing the LM5176 controller for automotive applications. This design can operate from 6V to 40V: and output 5V: 9V: 15V: and 20V at 5A. Output adjustment is achieved using TPS25740B power delivery controller. Two ports are operating independently: and each port is synced via an external clock with 180 degree out of phase. Switching frequency is set to 220kHz: and a 4 layer PCB is used.
