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.

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
