IW3627-00 - Renesas Electronics

Description: The iW3627 is a digital offline PWM controller that provides a constant voltage for smart LED lighting applications up to 90W with high power factor (PF >0.9) and low THD (<20%). It supports the most common single-stage isolated and non-isolated topologies (buck, buck-boost or flyback) as a front-end or standalone power supply in solid-state lighting (SSL) applications with advanced digital control technology.

IW3627-00 Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure a minimum of 1 oz copper thickness and a thermal relief pattern around the device.
  • Implement a robust thermal management system, including a heat sink and thermal interface material. Ensure good airflow and avoid thermal hotspots.
  • The critical timing parameters include the clock frequency, clock duty cycle, and setup/hold times for the input signals. Refer to the datasheet for specific values.
  • Use a logic analyzer or oscilloscope to monitor the input/output signals. Check for proper power supply voltage, clock signal integrity, and signal termination.
  • Use 0.1 μF to 1 μF ceramic capacitors with a voltage rating of 10 V or higher, placed as close as possible to the device's power pins.
