Description

The SC4524C is a constant frequency peak current-mode step-down switching regulator capable of producing 2A output current from an input ranging from 3V to 28V. The switching frequency of the SC4524C can be programmed up to 2MHz for component miniaturization or it can be set at lower frequencies to accommodate high step-down ratios. The SC4524C is suitable for next generation XDSL modems, high-definition TVs and various point of load applications.
