Description

General part information

LTC3632 Series

The LTC3632 is a high efficiency, high voltage step-down DC/DC converter with internal high side and synchronous power switches that draws only 12μA typical DC supply current at no load while maintaining output voltage regulation.The LTC3632 can supply up to 20mA load current and features a programmable peak current limit that provides simple method for optimizing efficiency in lower current applications. The LTC3632’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 4.5V to 50V input range and internal overvoltage monitor capable of protecting the part through 60V surges, the LTC3632 is a robust converter suited for regulating a wide variety of power sources. Additionally, the LTC3632 includes a precise run threshold and soft‑start feature to guarantee that the power system start-up is well-controlled in any environment.The LTC3632 is available in the thermally enhanced 3mm × 3mm DFN and MS8E packages.Applications4mA to 20mA Current LoopsIndustrial Control SuppliesDistributed Power SystemsPortable InstrumentsBattery-Operated DevicesAutomotive Power Systems
