IW3622-00

Overview

The IW3622-00 is an off-line digital power controller IC designed for LED driver applications. It integrates a digital control loop to achieve high power factor and low ripple current, eliminating the need for secondary-side feedback components. The device supports primary-side regulation (PSR) to simplify design and reduce cost while maintaining precise output voltage control.

Feature Summary

• Integrates a digital power controller for AC/DC LED drivers
• Enables high power factor operation without external PFC circuits
• Supports low ripple current for improved LED longevity
• Utilizes primary-side regulation to remove optocouplers

Applications

• Solid state lighting fixtures
• LED downlights
• Commercial lighting adapters

Procurement Notes

Verify availability status as supply may be limited or subject to factory special orders. Confirm RoHS compliance details and specific package variants such as Reel or Cut Tape options with the manufacturer or authorized distributors before finalizing procurement plans.

Selection Notes

Select this component for designs requiring simplified bill of materials through primary-side regulation. Ensure the application demands high power factor correction and low output ripple characteristics typical of modern LED lighting standards.

Part Context

This part belongs to the IW3622 series of digital power controllers from Renesas Electronics Corporation. It is functionally related to other models in the family such as the IW3620 and IW3627, which share similar digital control architectures but may differ in specific pinouts or integrated features.

Replacement Considerations

Check for direct substitutes within the IW362x series. Verify pin compatibility and electrical specifications against alternatives like the IW3620 or IW3627 if sourcing constraints exist.
