Overview
The RT7304AGE is a constant current LED driver IC with active power factor correction, manufactured by Richtek USA Inc. It supports high power factor across wide line voltages and drives converters in Quasi-Resonant mode for efficiency. Utilizing Primary Side Regulation, it controls output current accurately without secondary-side shunt regulators or opto-couplers. The device operates within a VDD voltage range up to 25V and features comprehensive protection functions including LED open/short circuit, output diode short circuit, UVLO, OVP, OTP, and cycle-by-cycle current limitation.
Feature Summary
- Primary-Side Regulation eliminates the need for opto-couplers and TL431
- Active Power Factor Correction ensures high power factor across line voltages
- Quasi-Resonant switching mode achieves higher efficiency
- Integrated protection against LED open/short circuits and over-temperature
Applications
- LED lighting systems requiring isolated outputs
- Offline AC-DC converter designs
- Applications supporting Flyback, Buck, or Boost topologies
Procurement Notes
Verify component authenticity through authorized distributors. Confirm RoHS compliance status as specified in official documentation. Check manufacturing date codes against current availability records. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly. Validate pinout compatibility with target PCB footprint design.
Selection Notes
Select this component for designs prioritizing reduced external component count via primary-side regulation. Suitable for applications requiring active PFC without secondary feedback loops. Consider thermal management capabilities given the operating temperature range. Evaluate protection feature set against specific safety requirements.
