1. DESCRIPTION
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 supply current at no load while maintaining output voltage regulation. The LTC3632IDD#PBF 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 LTC3632IDD#PBF’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 LTC3632IDD#PBF is a robust converter suited for Regulating a wide variety of power sources. Additionally, the LTC3632IDD#PBF includes a precise run threshold and soft-start feature to guarantee that the power system start-up is well-controlled in any environment. The LTC3632IDD#PBF is available in the thermally enhanced 3mm × 3mm DFN and MS8E packages.
