Description

The iW1697 is a high-performance AC/DC controller designed to drive an external power bipolar junction transistor (BJT) for peak current mode PWM flyback power supplies. Ideal for wall adapters in portable electronics and power supplies for consumer electronics, the iW1697 easily meets the Energy Star® specification for AC/DC single-output power supplies (Rev. 2.0) with no-load power consumption less than 20mW.

As a PrimAccurate™ controller, which uses primary-side control algorithms, the iW1697 does not need any direct secondary-side feedback components, eliminating the need for opto-isolators, reducing component count and solution cost. Additional features include Renesas' 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. The iW1697 comes in three options, the iW1697-01 with a 300mV voltage drop compensation offset, the iW1697-03 with a 450mV voltage drop compensation offset, and the iW1697-05 with 150mV of offset compensation.
