Product Summary

The MR4710 is a partial resonance power supply IC module with a function for switching to standby mode during micro-loads. It is comprised of a switching element and control IC optimized to 100 V class, 200 V class, and worldwide input power supplies. The MR4710 reduces the control IC loss more than conventional products, and incorporate high-performance switching elements such as Shindengen original second-generation high-speed IGBTs (insulated gate bipolar transistors) and CoolMOS devices. Applications of MR4710 include: DVD recorders, LCD TVs, digital set top boxes, multifunction printers, white goods, other.

Parametrics

MR4710 absolute maximum ratings: (1)Withstand Voltage: 700V; (2)Maximum output capacity, Po: AC180-276V: 25W; AC90-276V: 12W.

Features

MR4710 features: (1)Higher output capacity with FTO package (Po for MR1531 [FTO-5P] = up to 80 W→MR4040 [FTO-7P] = up to 180 W); (2)FTO package 7-pin configuration allows for distance between high-voltage pins; (3)Use of second-generation high-speed IGBT with 900 V withstand voltage improves efficiency; (4)Supports standby mode (Pin at no load is about 60 mW).
