Description

XLSEMI XL4201E1 Buck DC/DC Converter with Constant-Current Loop

XL4201E1 PWM buck DC/DC converter with constant-current loop, 8–40 V input, 1.25–37 V adjustable output and load capability up to 2.5 A.

XLSEMI XL4201E1 is a PWM buck DC/DC converter that steps a higher DC input down to an adjustable output. It accepts 8–40 V and supports output settings from 1.25 V to 37 V, with a load capability up to 2.5 A. The integrated constant-current loop also supports designs that need controlled output current.

Fixed-frequency switching and an integrated power MOSFET reduce the need for external control parts. Internal frequency compensation helps simplify the circuit, while thermal shutdown, current limiting and input overvoltage protection add built-in safeguards. The SOP8-EP package has an exposed pad.

Use this step-down DC/DC converter in car and battery chargers, portable instrument supplies and telecom equipment. Its combined voltage regulation and constant-current function can support buck constant-current driver designs and LED lighting circuits.
