NCP4543 ecoSwitcht Advanced Load Management Controlled Load Switch with Low RON The NCP4543 load switch provides a component and area-reducing solution for efficient power domain switching with inrush current limit via soft start. It is designed to integrate control and driver functionality with a high performance low on-resistance power MOSFET in a single device. This cost effective solution is ideal for power management and hot swap applications requiring low power consumption in a sm.
