iW1696数据手册Renesas中文资料规格书

描述 Description

The iW1696 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 iW1696 offers no-load power consumption less than 150mW.\r
As a PrimAccurate™ controller, which use primary-side control algorithms, the iW1696 does not need any direct secondary-side feedback components, eliminating the need for optocouplers, reducing component count and solution cost. 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.
