IW3623-00 - Renesas Electronics

Description: The iW3623 is a high-performance, two-stage, non-dimmable 45W Solid-State Lighting (SSL) LED driver that integrates boost and flyback converters into a single IC to reduce BOM cost and simplify design versus conventional two-stage driver approaches. Compliant to the IEC 61000-3-2 standard, the iW3623 offers a Power Factor (PF) of >0.95 from a universal input voltage of 100VAC to 277VAC, with Total Harmonic Distortion (THD) <10% and low output ripple <5% over the entire range.The iW3623 incorporates Renesas'

IW3623-00 Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (APL-AN-114) which includes thermal vias, thermal pads, and heat sink recommendations to ensure optimal thermal performance.
  • The IW3623-00 has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor and capacitor. The recommended values for the resistor and capacitor can be found in the datasheet. Additionally, an external overcurrent protection circuit can be implemented using a sense resistor and a comparator.
  • The recommended input capacitor value is 10uF to 22uF, and the type should be a low-ESR ceramic capacitor (e.g., X5R or X7R) to ensure stable operation and minimize voltage ripple.
  • The output voltage of the IW3623-00 can be adjusted by connecting a resistor divider network between the VOUT pin and the GND pin. The recommended resistor values can be calculated using the formula provided in the datasheet.
  • The maximum ambient temperature for the IW3623-00 is 85°C, but it can be derated to 70°C for high-reliability applications. It's essential to ensure proper thermal design and heat sinking to maintain a safe operating temperature.
