Overview
The iW3627-00 is a digital constant-voltage offline PWM controller with power factor correction, designed for LED lighting and general-purpose power supplies up to 100W. It supports isolated and non-isolated topologies including flyback, buck, and buck-boost. The device operates in continuous conduction mode (CCM) or discontinuous conduction mode (DCM), achieving a power factor greater than 0.9 and total harmonic distortion below 20%. It features PrimAccurate technology for output voltage regulation without secondary feedback, adaptive transient detection keeping variations within ±10% of nominal voltage, and configurable switching frequencies between 90 kHz and 120 kHz. No-load standby power consumption is less than 200 mW.
Feature Summary
- PrimAccurate constant voltage control eliminates the need for secondary feedback circuits
- Adaptive output voltage transient detection maintains stability under load changes
- Configurable minimum and maximum switching frequencies optimize efficiency and size
- Active start-up scheme reduces turn-on time without increasing standby power
Applications
- Solid state lighting
- Adapters and chargers
- Monitor power supplies
- TV power supplies
- Multi-port high-power USB-PD hubs
Procurement Notes
Verify the specific suffix -00 against the official Renesas datasheet to confirm pinout and electrical characteristics match your design requirements. Check current availability status as supply may be limited. Ensure the SOT-23-6L package dimensions and thermal properties are compatible with your PCB layout constraints before finalizing procurement.
Selection Notes
Select this component for designs requiring high power factor correction and compact form factors. It is suitable for applications needing precise constant voltage regulation without optocouplers. Consider the SOT-23-6L package for space-constrained boards. Verify that the input voltage range of 90V to 277V aligns with your mains specifications.
Part Context
The iW3627 series belongs to Renesas' portfolio of digital AC/DC controllers aimed at simplifying power supply designs. It integrates advanced digital control algorithms to replace traditional analog compensation networks. This family targets the growing demand for efficient, small-footprint power solutions in consumer electronics and lighting applications.
Replacement Considerations
Consult the official Renesas cross-reference documentation for verified substitute part numbers. Do not assume functional compatibility with other models based on package similarity alone. Verify electrical parameters and pin configurations before substitution.
