PFC Circuit Control IC MH Series

Overview

It is a PFC circuit control IC which enables multi-stage interleave.
By using a master IC that can be used independently and a slave IC that configures multilevel interleave synchronously with the master IC, high efficiency high power power supply is realized.

Product name	Standard specification code	Action mode		Input detection	Vcc（V）	Single operation	Package
MH2501SC	-5072	Master	Circuit critical mode	Unnecessary	13 ～ 23	Able	SOP8J
MH2511SC	-5072	Slave	Synchronize with master IC	Unnecessary	11 ～ 23	Unable	SOP8J

PFC circuit control IC MH2501SC/MH2511SC

Enables higher power by interleaving operation using MH 2501SC (master IC) and MH2511SC (Slave IC)
Realization of high efficiency and low noise by currenct critical operation
Direct drive of MOSFET possible
Reduced input line output detection loss due to input monitoring
Reduce detection loss by lowering the threshold value of the current detection terminal to 0.5 V
SOP8 J Package effective for miniaturization and space saving
SOP8JPackage

Main applications

Air conditioning
LED lighing equipment
Audio equipment
Power supply for document equipment such as LBP
Energy saving flat TVs
Other

Various Protection functions

Overcurrent protection
Overvoltage protection
Diode short protection
Feedback open protection
Feedback short protection

Basic circuit configuration

Multi interleave

Correstponding to interleave operation by combining master IC + slace IC
Interleave operation with 3 or more stages is also possible with multiple slave ICs
Suitable for high current applications while current criticality operation
