The OM5119 is a high-efficiency AC-DC PD (Power Delivery) integrated circuit from HCW-HENGCHENGWEI, designed for advanced multi-protocol fast charging and intelligent power management systems. Supporting adaptive output voltages of 5V, 9V, 12V, and 15V, this device enables flexible and stable power delivery for a wide range of fast-charging applications. It also supports multi-protocol compatibility and incorporates power-saving features including “省431” low-power optimization and intelligent power reduction for improved energy efficiency.
Engineered for modern AC-DC conversion systems, the OM5119 delivers stable voltage regulation, efficient power conversion, and reliable performance under varying load conditions. Its multi-protocol support ensures compatibility with different fast-charging standards, making it suitable for universal charger and adapter designs.
The device is housed in a robust SOP-8 package, providing enhanced thermal dissipation, strong electrical stability, and flexible pin configuration for more complex power designs. This makes it ideal for high-reliability AC-DC systems requiring both performance and integration flexibility.
