Linear Technology's LTC3630 is a high efficiency step-down DC/DC converter with internal high side and synchronous power switches that draws only 12 µA typical DC supply current while maintaining a regulated output voltage at no load.
The LTC3630 can supply up to 500 mA 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 V to 65 V, 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 comparator output enables multiple LTC3630s to be paralleled in higher current applications.
The LTC3630 is available in the thermally-enhanced 3 mm x 5 mm DFN and the MSE16 packages.
