PM2116XJ is an external OVP step-down LED constant current driver chip  The film. The chip operates in inductor current critical continuous mode, suitable for  Non isolated step-down type with full range input voltage of 85Vac~265Vac  LED constant current power supply. Chip OVP pin with Enable function, suitable for  Used for color adjustment and sensor light applications.  

The PM2116XJ chip integrates a 500V power switch internally and uses a gate  Demagnetization detection technology and high-voltage JFET power supply technology, without the need for VCC capacitors  And the starting resistor makes its peripheral devices simpler, saving peripheral resources  Cost and volume.  

The PM2116XJ chip is equipped with a high-precision current sampling circuit and a constant current  Control technology to achieve high-precision LED constant current output and excellent line performance  Voltage regulation rate. The chip operates in inductor current critical mode and outputs  The current does not vary with changes in inductance and LED operating voltage  Excellent load adjustment rate. 

 PM2116XJ has multiple protection functions, including LED short-circuit protection,  Chip power supply undervoltage protection, external OVP, chip temperature overheating regulation  Wait.  

PM2116XJ adopts SOP7 packaging.
