The LTM4625IY#PBF is a high-efficiency, single-chip 20V Buck DC/DC switching voltage regulator module from Analog Devices. With a nominal input voltage range of 18V to 36V and adjustable output voltage range of 0.6V to Vin - 0.5V, the LTM4625IY#PBF can deliver up to 5A of output current and has a 10uA low-noise quiescent current. It features integrated MOSFETs with reverse current shutdown protection, programmable switching frequency up to 2MHz, overcurrent and thermal protection, and adjustable soft start. The LTM4625IY#PBF also boasts an integrated loop compensation, allowing for a fast transient response. The device is provided in a space-saving, RoHS compliant, thermally enhanced 36-pin, 4mm x 6mm QFN package for applications such as document scanners, industrial instruments, and communication systems.
