The XLSEMI XL3002 datasheet details a 1.5 A, 380 kHz buck LED constant‑current driver with 5‑32 V input, up to 96 % efficiency and built‑in protection.
The XL3002 is a fixed‑frequency 380 kHz buck DC‑DC converter designed to drive LED loads up to 1.5 A. It operates from a wide 5 V to 32 V input range, provides a constant output current with low ripple, and includes internal MOSFET, thermal shutdown, current limit and EN‑pin control.
The datasheet supplies pin descriptions, typical application circuits for MR16 LED lamps, efficiency curves, ordering information, absolute maximum ratings, electrical characteristics, recommended Schottky diodes and package dimensions, giving designers all necessary data to integrate the device.
| Maximum Output Current | 1.5 A |
|---|---|
| Switching Frequency | 380 kHz |
| Efficiency | up to 96 % |
| Current Sense Voltage | 0.24 V |
Driving the EN pin high turns the regulator on; pulling it low shuts it down.
The converter can reach up to 96 % efficiency under rated conditions.
The XL3002 uses a fixed 380 kHz PWM switching frequency.
