The PMP10664 reference design is a 35W dual-output synchronous buck converter using the LM25119 controller IC. The design accepts an input voltage of 9.8Vin to 15.1Vin, provides one output of 3.3V capable of supplying 6.5A of current and one output of 3.3V capable of supplying 4A of current to the load. It features a small size and is an inexpensive and efficient solution. The design is capable of using a 3.3V, 1.5MHz external clock on the sync pin to drive the device. A Schottky diode is implemented in parallel with the low side sync FET’s body diode in each channel to improve efficiency.
