Description

XLSEMI XL4501E1 PWM Buck DC/DC Converter with Constant-Current Loop

XL4501E1 PWM buck converter with constant-current control, 8–36 V input, adjustable 1.25–32 V output and 150 kHz nominal switching.

The XLSEMI XL4501E1 is a PWM buck DC/DC converter with an adjustable output and an output constant-current loop. It accepts an 8 V to 36 V input and supports output settings from 1.25 V to 32 V. This makes it suited to designs that need a regulated step-down supply or controlled current from a DC input.

Its integrated power MOSFET, oscillator and frequency compensation reduce the number of external parts. The fixed-frequency control supports predictable switching design, while built-in current limiting, overcurrent protection and thermal shutdown help manage fault conditions. An external sense resistor sets the constant-current level, giving designers control over load current. The TO263-5L package supports board-level power conversion in charger, lighting and display systems.

Use the XL4501E1 in car and battery chargers, portable instrument supplies, LCD monitors and TVs, telecom equipment, or LED lighting. Its voltage and current regulation combine in one IC for power and constant-current designs.
