Description

• Parameters: SINGLE STAGE PRIMARY SIDE REGULATION HIGH POWER FACTOR LED DRIVER IC WITH PWM/LINEAR DIMMING
• Description: The SD7881 is a single stage primary side regulation high power factor LED driver with dimming function, it has PWM and linear dimming functions, with dimming depth up to 1%, it is mainly used in isolated flyback smart LED lighting system. The SD7881 provides accurate constant current control and operates in boundary conduction mode (BCM) with high efficiency. It adopts primary side regulation eliminating the opto-couple, secondary feedback control and loop compensation, which effectively simpli
