The LTC3822EDD from Analog Devices is a synchronous step-down switching regulator controller designed to drive external N-channel power MOSFETs. It utilizes a constant frequency current mode architecture with MOSFET VDS sensing, eliminating the need for sense resistors and enhancing efficiency. This controller supports high current outputs and operates with an input voltage range of 2.75V to 4.5V.
Key features include a selectable switching frequency of 300kHz, 550kHz, or 750kHz, a 0.6V reference voltage, and low dropout operation with a 99% duty cycle. The device incorporates internal soft-start circuitry, selectable maximum peak current sense threshold, digital RUN control, and output overvoltage protection. It also offers micropower shutdown with a typical quiescent current of 7.5μA.
The LTC3822EDD is available in a compact 3mm x 3mm thermally enhanced leadless package. Its operating temperature range is -40°C to 125°C, making it suitable for various demanding applications.
