The LTC3633 is a high efficiency, dual output monolithic synchronous step-down switching regulator, capable of delivering 3A of output current per channel from input voltages between 3.6V and 15V. Its compact 4mm × 5mm QFN package has very low thermal impedance eliminating the need for an external heat sink. Its high input voltage capability makes the LTC3633 ideal for 12V distributed power systems.
