MD6753 
Package : SOP28
RoHS : YES
The MD6753 is a fully digital-controlled power supply IC that controls interleaved totem-pole bridgeless PFC. Interleaving control in the critical conduction mode reduces input/output ripple current and switching loss, and the IC can achieve high-efficient, yet low-noise power systems.
Built-in microcomputer: MD6603
