< 30mW standby power

The iW1676 is a high performance AC/DC controller designed to drive a low-cost BJT power switch in peak current mode PWM flyback power supplies up to 5W. Ideal for power adapters for smartphones, the iW1676 integrates Dialog’s PrimAccurate™ digital primary-side control, eliminating the need for the secondary-side optocoupler, reducing component count and solution cost.

The iW1676 easily meets the US DoE’s external power supply standard and the EU’s Code of Conduct, version 5, tier 2 standard, with no-load power consumption less than 30mW. Additional features include Dialog's proprietary EZ-EMI™ technology, quasi-resonant control for optimal efficiency at heavy loads, cable and connector voltage drop compensation options, full protection from fault conditions and tiny packaging.
