PowerTech PT4201 LED Driver Datasheet
The PT4201 LED driver supports 1 W to 30 W output power and provides constant‑current regulation with low EMI and high efficiency. It includes over‑current (OCP), over‑voltage (OVP) and undervoltage lock‑out (UVLO) protections, and can be driven by an external PWM signal.
The device is supplied in a 6‑lead SOT‑23‑6 package, operates from a VDD range of 10 V‑30 V (up to 37 V absolute maximum), and features a programmable oscillator (Rosc) for setting the PWM frequency. Detailed pin definitions, electrical characteristics, and typical application circuits are provided in the datasheet. This manual is written in Chinese.
