Multi Interleave Technology !
”Over 2 Stage”
MH2501SC, MH2511SC
MH2501SC:master PFC_IC SOP8
MH2511SC:slave PFC_IC SOP8
■ High efficiency and low EMI integrated Critical Current
Mode PFC Controller
■ Multple interleaving operation possible by adding
multipe slave controller
■ No input voltage sensing permits reduction in power
MOSFET :
consumption
Cool MOS C3,CPseries
Hi-pot2 series
Diode :
■ Isrc/Isink=0.5A(sourcing)/1.2A(sinking) Gate driver
■OVP , OCP , loop open/short protections , Slave stop
FRD SF*K60Mseries protection ,Blocking diode short protection
MV1000series
MV1001SC: Can operated via AC direct input
MV1002SC: Uses an external starter circuit
Deep Dimming Control !
■ Constant current control
■ Critical Conduction Mode ⇒ High efficiency and low EMI
■ Allows for PWM dimming input and linear dimming input
■ Can operated via AC direct input (MV1001SC)
■ high side and low side drive -- both are possible
■ Switching frequency clamp by OFF width control
■ Equipped with various protection, such as LED short protection
