NCL30095A Power Factor Corrected LED Boost Switching Regulator The NCL30095A high power factor boost PWM switching regulator is designed to regulate the average current through a string of LEDs.
The circuit operates in Critical Conduction Mode (CrM) based on a proven constant on time control scheme to achieve near unity power factor.
In addition to regulating a constant current, the switching regulator is optimized to support leading and trailing edge phase dimming applications.
