This reference design is a USB Type-C® dual-output buck with 65-W output power and 98.8% efficiency. The design uses two LM61460 buck converters to step down a 21-V input and includes a 5-V bias voltage input to maximize efficiency. The USB Type-C design offers dual-output voltages of 5 V, 9 V, 15 V, 20 V and was tested using the PMP22426 daughter card. PMP22426 uses the TPS25740B, USB Type-C power delivery controller, to control each output seperately.
