IRS2166DPBF

Lighting, Ballast Controllers Overview

The IRS2166DPBF is a fully integrated, protected 600V ballast control IC designed to drive all types of fluorescent lamps. It combines PFC, ballast control, and half-bridge driver functions in a single chip. The device operates with critical conduction mode boost type PFC, eliminating the need for a PFC current sense resistor. Key features include programmable preheat frequency, preheat time, run frequency, dead time, over-current protection, and end-of-life protection. It also incorporates an internal ignition ramp, fault counter, DC bus under-voltage reset, and shutdown pin with hysteresis.

Lighting, Ballast Controllers Feature Summary

• Integrates PFC, ballast control, and half-bridge driver functions
• Supports critical conduction mode boost type PFC without current sense resistor
• Features programmable preheat, run frequencies, and protection parameters
• Includes comprehensive lamp failure and end-of-life protection mechanisms

Lighting, Ballast Controllers Applications

• Fluorescent lamp ballast control
• PFC circuitry for lighting applications
