Monolithic Power Systems Releases First All-in-One Flyback Power IC with Capacitive Isolation, Targets USB PD and Standard Adapters in 25W - 65W Output Power Range
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. PWM/PFM control provides excellent EMI across the entire load range, free of audible noise that often exists with alternative control schemes. The MPX2001 benefits from seventh generation industry-leading SR driver designs optimized for safe, efficient CCM SR operation that minimizes body diode conduction of the SR MOSFET while eliminating any cross-conduction concerns. Capacitive isolation replaces traditional optocouplers to ensure reliable, long-term operation.
"The MPX2001 is ideal for very tight USB PD and QC-compatible adaptor designs," says
The MPX2001 is UL1577 and UL/IEC/EN62368 safety-certified, is available in an MSL1-rated SOIC20WB package and is priced at
