PFC Circuit Control IC MH Series


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 11 ~ 23 Unable
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
