Sanken MD6753
The MD6753 is a fully digital-controlled power supply IC that controls interleaved totem-pole bridgeless PFC.DESCRIPTION
Interleaving control in the critical conduction mode reduces input/output ripple current and switching loss, and the IC can achieve highefficient, yet low-noise power systems.FEATURES
● Fully Digital-controlled PFC Circuit● Interleaved Totem-pole PFC Control
● Critical Conduction Mode (CRM) Control
● Bridgeless PFC Circuit
● High Efficiency in All Load Ranges Achieved by Synchronous Rectification and Intermittent Operation at Light Load
● Soft Start
● Protections Include: - AC Power Supply Input Undervoltage Lockout - AC Power Supply Input Off-state Detection - PFC Output Undervoltage Protection (PFC_UVP) - PFC Output Overvoltage Protection (PFC_OVP) - PFC Overcurrent Protection (PFC_OCP) - PFC Overload Protection (PFC_OLP) - AC Regeneration Side High-side Driver Undervoltage Lockout - VCC Pin Overvoltage Protection (VCC_OVP) - Thermal Shutdown (TSD) Package SOP28 Not to scale
