Description

XLSEMI XL4001E1 Adjustable Buck DC/DC Converter IC

XL4001E1 adjustable buck DC/DC converter IC with 4.5 V to 40 V input, 1.235 V to 37 V adjustable output, 2 A load capability and a constant-current loop.

XLSEMI XL4001E1 is an adjustable buck DC/DC converter IC. It steps a higher DC input down to a set output and supports a constant-current loop. Its input range is 4.5 V to 40 V, with an adjustable output from 1.235 V to 37 V.

The step-down converter design combines voltage conversion with current control. Internal frequency compensation supports a simpler converter design. An enable input lets the system control operation, while built-in current limiting, thermal shutdown and output overvoltage protection help manage fault conditions.

Use this buck converter IC in car chargers, battery chargers and LED constant-current drivers. Its voltage and current control functions suit power designs that need both adjustable output and controlled load current.
