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.
