Overview

NCL30167 Power Factor Corrected LED Boost Switching Regulator The NCL30167 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.
When a dimmer is detected on the AC input, an internal voltage reference of the current regulation loop adjusts the current level based on the dimmer conduction angle so the current through the LED string has a desire...
