LTC3442 Product details

DESCRIPTION
The LTC®3442 is a highly efficient, fixed frequency, BuckBoost DC/DC converter, which operates from input voltages above, below, and equal to the output voltage. The topology incorporated in the IC provides a continuous transfer function through all operating modes, making the product ideal for a single Lithium-Ion or multicell alkaline applications where the output voltage is within the battery voltage range.

FEATURES
■ Regulated Output with Input Voltages Above, Below, or Equal to the Output
■ Single Inductor, No Schottky Diodes Required
■ Manual or Programmable Automatic Burst Mode® Operation
■ Programmable Average Input Current Limit
■ Up to 1.2A Continuous Output Current from a Single Lithium-Ion Cell
■ High Efficiency: Up to 95%
■ Output Disconnect in Shutdown
■ 2.4V to 5.5V Input Range
■ 2.4V to 5.25V Output Range
■ 35µA Quiescent Current in Burst Mode Operation
■ Programmable Frequency from 300kHz to 2MHz
■ <1µA Shutdown Current
■ Small, Thermally Enhanced 12-Lead (4mm × 3mm) DFN Package

APPLICATIONS
■ PDA/‘SMART’ Phones
■ Handheld Computers
■ MP3 Players
■ Handheld Instruments
■ Digital Cameras
■ Wireless Handsets
■ USB Peripherals
