Description

General part information

LTC3407A-2 Series

The LTC3407A-2 is a dual, constant frequency, synchronous step-down DC/DC converter. Intended for low power applications, it operates from a 2.5V to 5.5V input voltage range and has a constant 2.25MHz switching frequency, enabling the use of tiny, low cost capacitors and inductors 1mm or less in height. Each output voltage is adjustable from 0.6V to 5V. Internal synchronous 0.35Ω, 1A 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 ripple noise for low power efficiency. Burst Mode®operation provides the highest efficiency at light loads, while Pulse Skip Mode provides the lowest ripple noise at light loads.To further maximize battery life, the P-channel MOSFETs are turned on continuously in dropout (100% duty cycle), and both channels draw a total quiescent current of only 40µA. In shutdown, the device draws <1µA.IOUTFSWFeaturesLTC34072x 600mA1.5MHzLTC3407-22x 800mA2.25MHzLTC3407-32x 800mA2.25MHzFixed 1.8V/3.3VLTC3407-42x 800mA2.25MHzReduced POR DelayLTC3407A2x 800mA1.5MHzLow Ripple Burst ModeLTC3407A-22x 800mA2.25MHzLow Ripple Burst ModeApplicationsPDAs/Palmtop PCsDigital CamerasCellular PhonesWireless and DSL Modems
