IR2166STRPBF

Lighting, Ballast Controllers Overview

The IR2166STRPBF is a fully integrated, protected 600V ballast control IC designed to drive fluorescent lamps. It combines PFC, ballast control, and half-bridge driver functions in a single package. The device operates in critical conduction mode boost type PFC without requiring a current sense resistor. It features programmable preheat frequency, run frequency, and dead time. The IC includes internal ignition ramp, fault counter, and DC bus under-voltage reset capabilities. It supports shutdown pin with hysteresis and micropower startup at 150µA. The component is housed in an 8-lead SOIC (narrow body) surface-mount package.

Lighting, Ballast Controllers Feature Summary

• Integrates PFC controller, ballast control logic, and half-bridge gate driver into a single 600V IC
• Enables critical conduction mode boost PFC operation without external current sense resistor
• Provides comprehensive protection including lamp strike failure, filament faults, and end-of-life detection
• Features programmable parameters for preheat/run frequencies, preheat duration, and dead time

Lighting, Ballast Controllers Applications

• Fluorescent lamp ballast systems
• Critical conduction mode power factor correction circuits
• Integrated lighting control applications requiring high voltage isolation

Lighting, Ballast Controllers Procurement Notes

Verify the specific suffix STRPBF corresponds to the 8-lead SOIC narrow body package configuration as documented. Confirm RoHS compliance status through official Infineon documentation prior to integration. Ensure design accounts for the 600V floating channel operational limits and bootstrap requirements inherent to the half-bridge driver architecture specified in the datasheet.

Lighting, Ballast Controllers Selection Notes

Select this component for applications requiring a unified solution for ballast control and PFC in fluorescent lighting. The absence of a required current sense resistor simplifies the PFC circuit design. Consider the programmable nature of preheat and run frequencies when designing timing components. Verify that the 600V rating aligns with the system's DC bus voltage requirements and that the SOIC-8 package fits the PCB layout constraints.

Lighting, Ballast Controllers Part Context

The IR2166 series belongs to Infineon's family of integrated ballast control ICs. These devices are engineered specifically for fluorescent lamp applications, combining high-voltage power management with precise control logic. The STRPBF designation indicates a lead-free variant packaged in a surface-mount format, distinguishing it from older PDIP versions within the same functional family.
