1 / 22 page  LTC3632 1 3632fb TYPICAL APPLICATION FEATURES APPLICATIONS DESCRIPTION High Efficiency, High Voltage 20mA Synchronous Step-Down Converter The LTC ®3632 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 sup- ply 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 a simple method for optimizing efficiency in lower current applications. The LTC3632’s combination of Burst Mode ® operation, integrated power switches, low quiescent cur- rent, 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.
