- Commodity name: SP5213F
- 封装: SOP8
- 品牌: Wuxi Silicon Power Microelectronics
It is a high-cell-density trench N-channel MOSFET that provides excellent RDSON and gate charge for most synchronous buck converter applications.
The SP5213F is a high-precision primary feedback LED constant current driver chip that uses a primary-side control mode, eliminating the need for a secondary feedback loop. Its special constant current control method achieves excellent linearity, and its extremely low operating current eliminates the need for transformer auxiliary winding detection and power supply, further reducing external components and saving system cost and size. The chip incorporates a high-precision current sampling circuit, ensuring LED output current accuracy within ±5%. Operating in discontinuous inductor current mode, it's suitable for flyback isolated LED constant current power supplies with 85Vac~264Vac input voltage and power below 3W, primarily used in LED lighting circuits.
The SP5213F features multiple protection functions, including LED open/short circuit protection, CS resistor short circuit protection, undervoltage protection, and chip overtemperature protection.
The SP5213F uses an SOP-8 package.
