SY50283FAC is a high-performance voltage regulator with constant current/constant voltage (CC/CV) control launched by Silijie. It can stably output over a wide input voltage range and flexibly support switching between constant voltage and constant current modes to meet the power supply needs of different loads. The chip is equipped with comprehensive protection mechanisms, such as overcurrent, overvoltage, and overtemperature protection, to ensure the safe and reliable operation of the system. With high efficiency and excellent dynamic response characteristics, it is particularly suitable for battery charging, power adapters, and various application scenarios that require constant current/constant voltage control.

·Integrated 500V mosfet

·CC/CV control eliminates auxiliary winding

·Quasi resonant (QR) mode can achieve low switching losses

·Low starting current: typical value is 15 μ A

·Maximum frequency limit: 45kHz

·Compact packaging: SO8
