Product Overview

The IW1830-EVAL from Dialog Semiconductor is an evaluation board implements a dual-output, 15W power supply based on iW1830 AccuSwitch digital offline power supply controller IC. The evaluation board supplies two outputs, 12V/1A and 5V/0.5A, using a single primary-side controlled quasi-resonant flyback converter. The design implements two output voltages using one primary-side controller and achieves the tight regulation required by high-reliability applications. It integrates a 700V power MOSFET to lower the power supply BOM cost and uses Dialog's advanced PrimAccurate digital control technology to eliminate need for external secondary-side feedback components, further reducing component count and cost, while improving reliability. It operates in quasi-resonant mode to improve efficiency and help meet EMI standards. This quasi-resonant operation and Dialog's EZ-EMI technology enable excellent EMI performance with minimal external filtering.
  • Wide input voltage range from 90VAC to 264VAC
  • Active mode efficiency is 84%
  • Supports high capacitance loads up to 6000µF
  • Low no-load power is less than 100mW (at 230VAC)
  • Output short-circuit, over-current, over-voltage
  • Input voltage protection brown-out, brown-in, unplug
  • Overtemperature protection
  • Designed to meet UL1310, EN60335-1:2012 safety standard


Power Management, Industrial, Consumer Electronics


When the evaluation board is powered, never touch the board or its electrical circuits since they may be operating at high voltages that can cause an electrical shock hazard.
