Overview

TopologyOther Topology
Input voltage90-264 V
Output 112 V / 3 A
IC revision1

Description

The iW1702 is a digital offline controller for AC/DC power supplies up to 45W optimized for 9V or greater output voltages. The part uses Renesas' PrimAccurate™ primary-side control technology, eliminating the need for an optical isolation device on the secondary, reducing component count and cost.For highest power density power supplies, the iW1702 can be paired with the iW676 digital synchronous rectifier controller, which drives a power MOSFET on the secondary side of the power supply to replace the main rectifying diode.

Features

  • 45W maximum output power
  • External supplemental output overvoltage protection, optimized for 9V+ output voltages
  • External input overvoltage protection, supports 5V+ output voltages
  • Programmable light load mode to optimize no-load power consumption and DLR
  • < 75mW no-load power consumption
  • Compliant with DoE Level VI and EU’s CoC, Version 5, Tier 2 external power supply standards
  • PrimAccurate™ primary-side regulation technology
  • Eliminates the need for optocoupler
  • SmartDefender™ smart hiccup technology
  • Protects from soft shorts in cables and connectors
  • Additional protection features
  • Output short circuit protection
  • Output overcurrent protection
  • Over-temperature protection

Typical applications

  • Smart Massage Chair
  • Wi-Fi Garage Door Control
  • AC Drive & General Purpose Inverter System, Motor Control System with Industrial Network and Functional Safety, Motor Control with Resolver
  • Online Uninterruptible Power Supply (UPS)
