IW1710-01 - Renesas Electronics

Description: The iW1710 is a high-performance, high-power AC/DC controller designed to drive an N-channel power MOSFET for peak current mode 10W to 40W PWM flyback power supplies. Ideal for power adapters in networking applications such as wireless gateways, cable modems and ADSL modems, the iW1710 offers no-load power consumption less than 150mW.As a PrimAccurate™ controller, which use primary-side control algorithms, the iW1710 does not need any direct secondary-side feedback components, eliminating the need for optoc

IW1710-01 Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (R01AN4393EJ0100) which includes thermal vias, thermal pads, and heat sink recommendations to ensure optimal thermal performance.
  • The IW1710-01 has a built-in overcurrent protection (OCP) feature that can be enabled by setting the OCP threshold through the I2C interface. Additionally, an external OCP circuit can be implemented using a sense resistor and a comparator to detect overcurrent conditions.
  • Renesas recommends using a ceramic capacitor with a value of 4.7uF to 10uF, X5R or X7R dielectric, and a voltage rating of 10V or higher, placed as close as possible to the VIN pin to ensure stable input voltage and reduce noise.
  • The IW1710-01 can be configured for low-power mode or shutdown by setting the appropriate registers through the I2C interface. The EN pin can also be used to shut down the device by pulling it low. Refer to the datasheet and application notes for specific register settings and shutdown procedures.
  • The maximum allowed voltage on the EN pin is 5.5V, and it's recommended to keep it within the 0V to VCC range to ensure proper operation and prevent damage to the device.
