Description

General part information

LTC3630 Series

The LTC3630A 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 LTC3630A 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 LTC3630A’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 76V, the LTC3630A is a robust converter suited for regulating a wide variety of power sources. A feedback comparator output enables multiple LTC3630As to be paralleled in higher current applications.The LTC3630A is available in the thermally-enhanced 3mm × 5mm DFN and the MSE16 packages.Vin RangeLTC36304.5V to 65VLTC3630A4.5V to 76VAPPLICATIONSIndustrial Control SuppliesMedical DevicesPortable InstrumentsAutomotiveAvionics
