超紧凑适配器

IW1691是一个高性能AC / DC控制器，旨在驱动N沟道功率MOSFET，用于峰值电流模式PWM反激电源。IW1691符合美国DOE的外部电源标准和欧盟的行为准则，雷竞技安卓下载第5版，第5版，第5版，第5版，第5版，第5版符合欧盟的外部电源标准和欧盟的行为准则，不符合负载功耗超过100MW。

As aprimAccurate™controller, which use primary-side control algorithms, the iW1691 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 and full protection from fault conditions, including an overtemperature protection feature with and without a latching option. The iW1691 comes in several different combinations of cable compensation voltage (0mV to 400mV) and protection features.
