Overview

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.

Key Features

  • is included to ensure proper handling of expected fault conditions without the need for extra circuitry and a dedicated thermal fold.
