The LTC3822-1 is a synchronous step-down switching regulator controller that drives external N-channel power MOSFETs using few external components. The constant frequency current mode architecture with MOSFET VDS sensing eliminates the need for sense resistors and improves efficiency.
Burst Mode operation provides high efficiency at light loads. The 99% maximum duty cycle provides low dropout operation, extending operating time in battery-powered systems.
The operating frequency can be programmed up to 750kHz, allowing the use of small surface mount inductors and capacitors. For noise sensitive applications, the LTC3822-1 can be synchronized to an external clock from 250kHz to 750kHz.
The LTC3822-1 is available in the tiny footprint thermally enhanced 12-pin DFN package or 16-pin narrow SSOP package.
