The LTC3637 can supply up to 1A 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 LTC3637’s combination of Burst Mode® operation, integrated power switch, 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, and programmable overvoltage lockout, the LTC3637 is a robust regulator suited for regulating from a wide variety of power sources.
Additionally, the LTC3637 includes a precise run threshold and soft-start feature to guarantee that the power system start-up is well-controlled in any environment.
The LTC3637 is available in the thermally-enhanced 3mm × 5mm DFN and the MSE16 packages.
