The LMR33630BDDAR is a 8-pin SOIC-sized switching voltage regulator with a SIMPLE SWITCHER 3.8V to 36V, 3A synchronous buck converter from Texas Instruments. This device features an ultra-low EMI 8-pin PowerPAD (-40 to 125C) design that allows for high-efficiency performance for high power density and low external component count. It is designed for applications such as automotive, telecom, datacom, point of load, and medical systems. The device has an adjustable feedback voltage level of 1.6V to 4.1V with load currents up to 3A. It is also capable of providing a high level of power system functional integration with configurable switching frequency. The device also features an integrated power switch with low RDS(on) to maximize efficiency, and can operate over the wide temperature range from -40C to 125C.
