Selectable cable drop compensation
IW1762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反激电源。IW1762为11W-24W之间的输出功率优化，是网络设备和监视器中的功率适配器的理想选择。
The iW1762 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 20mW while complying with active mode efficiency requirements. As a PrimAccurate™ controller the iW1762 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, adaptive multi-mode PWM/PFM control for optimal efficiency across all loads, 5 selectable cable and connector voltage drop compensation voltages, robust operation with full protection from over-voltage and over-temperature.
