The LTC3630EDHC is a high efficiency 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 LTC3630EDHC 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 4V to 65V, the LTC3630EDHC is a robust converter suited for regulating a wide variety of power sources. Additionally, the LTC3630EDHC 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 comparator output enables multiple LTC3630s to be paralleled in higher current applications.
The LTC3630EDHC is available in the thermally-enhanced 3mm × 5mm DFN and the MSE16 packages.
