Haolin Electronics HL201 PWM Controller Datasheet
The HL201 is a high‑performance current‑mode PWM controller designed for cost‑effective AC/DC converters. It operates in a flyback topology, features low‑power start‑up, light‑load frequency reduction, and built‑in protections for over‑current, over‑voltage, under‑voltage, and over‑temperature. The device is supplied in a lead‑free DIP‑8 package.
The datasheet includes absolute maximum ratings, recommended operating conditions, a block diagram, detailed pin assignments, electrical parameters, typical application schematics, package dimensions, and information on the built‑in over‑current protection circuit. This manual is written in Chinese.
