All-in-One Flyback Power IC with Capacitive Isolation for 25W to 65W AC-DCs

The MPX2001 combines four flyback ICs into one power IC with UL-qualified 4.5kVrms capacitive isolation and 8.4mm primary-to-secondary PCB clearance. Advanced continuous conduction mode (CCM) secondary-side control improves dynamic performance over traditional solutions and provides quick short circuit and over voltage protection.
Multi-chip integration eliminates multiple passive components, resulting in PCB board space saving and a BOM reduction up to 50%. The MPX2001 achieves as low as 15mW standby power loss while allowing design optimization with customer-preferred primary and secondary MOSFETs.
