The LTC3857EUH#TRPBF is an integrated, dual channel, synchronous step-down controller used to regulate switching voltage regulators with low quiescent current. This device is a low input voltage, low output current, pin-programmable regulated current source. It integrates a high-side and low-side driver, complete phase-shift control, and accurate current sensing. The device is ideal for microprocessor, DSP and FPGA core voltage applications. In addition, it is packaged in a small 10-lead plastic MSOP package and is manufactured by Analog Devices.
