Typical Application Using LTC3639EMSE 4 to 150V Input to 1.2V/50mA Output Regulator with Low Output Voltage Ripple

Typical Application Using LTC3639EMSE 4 to 150V Input to 1.2V/50mA Output Regulator with Low Output Voltage Ripple. The LTC3639 can supply up to 100mA 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 LTC3639 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. Wide input range of 4 to 150V and programmable overvoltage lockout, the LTC3639 is a robust regulator suited for regulating from a wide variety of power sources
