The LTC3565IMSE#TRPBF is an integrated, synchronous switching regulator and step-up (boost) DC-DC converter from Analog Devices. It features an integrated controller, MOSFET switches, inductor, and opto-coupler for precise current regulation. The device is optimized for use in systems powered from a Li-ion battery. It features up to 95% conversion efficiency, ultra-low quiescent current, high power density and precise current regulation down to 5µA. Input voltage range is 4.5V to 14V and output voltage range is 3.3V to 21V. Internal circuitry operates at 1MHz allowing the external components to be small and low profile. The part is packaged in a 2.00mm x 2.00mm, 10-lead, PowerPAD™ DFN exposed paddle package.
