Product Overview

The LTC3630EMSE#PBF is a 65V 500mA synchronous Step-down DC/DC Converter with internal high side and synchronous power switches that draws only 12µA typical DC supply current while maintaining a regulated output voltage at no load. The LTC3630 can supply up to 500mA load current and features a programmable peak current limit that provides a simple method for optimizing efficiency and for reducing output ripple and component size. The LTC3630's combination of Burst Mode® operation, integrated power switches, low quiescent current and programmable peak current limit provides high efficiency over a broad range of load currents. With its wide input range of 4 to 65V, the LTC3630 is a robust converter suited for regulating a wide variety of power sources. Additionally, the LTC3630 includes a precise run threshold and soft-start feature to guarantee that the power system start-up is well-controlled in any environment.
