Description

General part information

LTC3419 Series

The LTC3419 is a dual, 2.25MHz, constant-frequency, synchronous step-down DC/DC converter in a tiny 3mm × 3mm DFN package. 100% duty cycle provides low dropout operation, extending battery life in portable systems. Low output voltages are supported with the 0.6V feedback reference voltage. Each regulator can supply 600mA output current.The input voltage range is 2.5V to 5.5V, making it ideal for Li-Ion and USB powered applications. Supply current during operation is only 35µA and drops to <1µA in shutdown. A user-selectable mode input allows the user to trade off between high efficiency Burst Mode operation and pulse-skipping mode.An internally set 2.25MHz switching frequency allows the use of tiny surface mount inductors and capacitors. Internal soft-start reduces inrush current during start-up. Both outputs are internally compensated to work with ceramic output capacitors. The LTC3419 is available in a low profile (0.75mm) 3mm × 3mm DFN package. The LTC3419 is also available in a fixed output voltage configuration selected via internal resistor dividers.ApplicationsCellular TelephonesDigital Still CamerasWireless and DSL ModemsPortable Media PlayersPDAs/Palmtop PCs
