RS2201

Page No. : 1/1 RS2201 Switching Power Supply Controller Description RS2201, produced by advanced integrated circuit process, is a switch power supply controller, which could offer over-load and saturation protection, and achieve green economize on energy and environmental protection standard. RS2201 could achieve AC/DC conversion and can be widely applied to economical switching power supply equipment. For instance, Charger、DVD, Induction cooker, STB, Printer, LCD and so on. Features Over-load and saturation protection could protect over-load, switch transformer saturation and output short circuit or the relative failures. It is economical that triode is used for switch device, which could start up the circuit with its amplification function and reduce ten times of power consumption of the start-up resistance. Built-in Synchronized Slope Compensation circuit, thermal protection circuit, slope current drive circuit. Zero-load output power consumption could be less than 0.3W, is less than 0.2W while 220V AC input. Pin to Pin THX201 Pb-Free DIP-8 and SOP-8 Package.
