The LTC3630 can supply up to 500m A load current and Features a programmable peak current limit that provides a simple method for optimizing efficiency and for reducing output ripple and ponent size. The LTC3630’s bination 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 4V 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. A feedback parator output enables multiple LTC3630s to be paralleled in higher current applications. The LTC3630 is available in the thermally-enhanced 3mm × 5mm DFN and the MSE16 packages.
