Overview
ISO 9001 Registered IMP3522D ADAPTIVE BALLAST CONTROL IC General Description The IMP3522D(S) is a complete adaptive ballast controller, 450V half-bridge driver and power MOS FET integrated into a single IC for Compact Fluorescent Lamps (CFL) applications.
The IC includes adaptive zero-voltage switching (ZVS), internal crest factor over-current protection, as well as an integrated bootstrap FET.
The heart of this IC is a voltage controlled oscillator with externally programmable minimum frequency.
All of the necessary ballast features are integrated in a small 8-pin DIP package.
Key Features -450V Half Bridge Driver -Integrated Bootstrap FET -Integrated Power MOS FET -Adaptive zero-voltage switching (ZVS) -Internal Crest Factor Over-Current Protection -0 to 6VDC Voltage Controlled Oscillator -Programmable minimum frequency -Micropower Startup Current (80uA) -Internal 15.
