Overview
The RT7302GS is a constant current LED driver controller with active power factor correction, designed for primary-side regulation. It supports high power factor across wide line voltage ranges and drives converters in Quasi-Resonant mode for efficiency. The device eliminates the need for secondary-side shunt regulators and opto-couplers, reducing component count. It features comprehensive protection including LED open/short circuit, output diode short, VDD UVLO/OVP, over-temperature, and cycle-by-cycle current limit.
Feature Summary
- Primary-Side Regulation capability without opto-coupler or TL431
- Active Power Factor Correction support
- Quasi-Resonant switching mode operation
- Integrated multi-protection functions
Applications
- LED lighting drivers
- AC-DC offline switchers
- Buck-Boost converter topologies
Procurement Notes
Verify the specific suffix (e.g., Z00) against the manufacturer's official datasheet to confirm pinout and package details. Ensure the selected variant matches the required SOP-8 configuration. Cross-reference ordering information directly with Richtek USA Inc. documentation to avoid discrepancies from distributor listings.
Selection Notes
Select this component for applications requiring high power factor and reduced bill-of-materials through primary-side regulation. It is suitable for designs needing robust protection against LED faults and thermal issues. Verify compatibility with the intended transformer design and input voltage range before integration.
Part Context
The RT7302 belongs to Richtek's family of AC-DC LED driver controllers. It is part of a series that includes variants like the RT7304, sharing similar core functionalities such as active PFC and primary-side regulation. These devices target cost-sensitive, high-efficiency lighting applications.
Replacement Considerations
The RT7304GE is a related device offering similar primary-side regulation and active PFC capabilities. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
