SY2A22404 Overview
The SY2A22404 high-efficiency synchronous step-down DC-DC converter operates over a wide input voltage range (4.2V to 40V) and can deliver 3.5A load current. The device integrates the main switch and synchronous switch with very low RDS(ON) to minimize conduction loss. The SY2A22404 employs a peak-current-mode control strategy with a constant switching frequency that is adjustable from 300kHz to 2.2MHz using an...
