SC4524ESETRT

The SC4524E 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 SC4524E can be programmed up to 2MHz for component miniaturization or it can be set at lower frequencies to accommodate high step-down ratios. The SC4524E is suitable for next generation XDSL modems, high-definition TVs and various point of load applications.Peak current-mode PWM control employed in the SC4524E achieves fast transient response with simple loop compensation. Cycle-by-cycle current limiting and hiccup overload protection reduces power dissipation during output overload. Soft-start function reduces input startup current and prevents the output from overshooting during power-up.The SC4524E is available in SOIC-8 EDP package.
