LTC3548 - Dual Synchronous, 400mA/800mA, 2.25MHz Step-Down DC/DC Regulator

The LTC3548 is a dual, constant frequency, synchronous step down DC/DC converter. Intended for low power applications, it operates from 2.5V to 5.5V input voltage range and has a constant 2.25MHz switching frequency, allowing the use of tiny, low cost capacitors and inductors with a profile 1.2mm. Each output voltage is adjustable from 0.6V to 5V. Internal synchronous 0.35 ohm, 0.7A/1.2A Power Switches provide high efficiency without the need for external Schottky Diodes
A user selectable mode input is provided to allow the user to trade-off noise ripple for low power efficiency. Burst Mode operation provides high efficiency at light loads, while Pulse Skip Mode provides low noise ripple at light loads.
To further maximize battery runtime, the P-Channel MOSFETs are turned on continuously in dropout (100% duty cycle), and both channels draw a total quiescent current of only 40A. In shutdown, the device draws <1A.
