MR4710

MR4710 – Integrated Circuit Module for Switching Power Supplies (Partial Resonance Power Supply IC Module) Shindengen

The MR4710 is an integrated power module manufactured by Shindengen Electric Mfg. Co., Ltd., designed for switching power supplies (SMPS) operating in partial resonance. It is part of the MR4000 series and is designed for use in televisions, monitors, video equipment, set-top boxes, printers, and other consumer electronics.

The module integrates the control circuit and the power switching device, reducing the number of required external components and simplifying power supply design. Partial-resonant operation contributes to high efficiency and low electromagnetic noise.
