Selectable cable drop compensation

IW1699是一个高性能AC / DC控制器，旨在驱动外部电源N通道MOSFET，用于峰值电流模式PWM反激式电源。它使用对话框PrimAccurate™primary-side control technology, eliminating the need for a secondary-side regulator and optocoupler, reducing component count and solution cost while easily meeting the US DoE’s external power supply efficiency standard and the EU’s Code of Conduct, version 5, tier 2 external power supply standard, with no-load power consumption less than 30mW.

它在某些选项上集成了恒定的电流模式，因此它可以在适配器应用中使用，恒定电流精度> 3％。亚博国际官网平台网址其他功能包括对话框的专有EZ-EMI™technology, adaptive multi-mode PWM/PFM control for optimal efficiency across all loads, 5 selectable cable and connector voltage drop compensation voltages, and robust operation with full protection from over-voltage and over-temperature.
