Cxle8260 is a de stroboscopic LED lighting driver IC integrated with intelligent high-voltage LDO chip power supply technology, with single-stage active power factor correction function, which is suitable for boost and non isolated flyback topology. The chip adopts a number of unique technologies, the main advantages of which include:
1. High power factor, low harmonic content, zero output current ripple. It can be applied to various power levels.
2. The chip has a single-stage power factor correction function, which can achieve small circuit board size.
3. No strobe
4. Internal integrated high-voltage starting circuit for fast start
5. Single winding inductance, without auxiliary winding, reducing cost
6. Multiple protection functions to improve reliability
7. With few peripheral devices and low overall cost, critical continuous mode is adopted for drive chip control, which is typically used in boost and flyback topologies.
With quasi resonant mode, external power MOSFET, the switching loss is small. Driver chip can be applied to compact LED lamp, suitable for single voltage operation, 100vac, 120VAC, 230VAC. It can also work under full pressure with the input range of 90 ~ 305vac. The output power range is 2W ~ 40W, and the power level of the drive is determined by the peripheral components
