Quasi-Resonant Power Supply ICs

MR4000 Series

  The MR4000 Series IC modules are designed for a burst-mode (standby mode) switching function at micro-loads. Its quasi-resonant operation makes possible low noise and superior efficiency. It is ideal for a variety of power applications including consumer devices.

MS Series

 The MS1003SH and MS1004SH consume less power in standby mode than conventional ICs.
The ICs incorporate various functions to make it more user-friendly and to make it easier to design a power supply with fewer external components.
