Description
The SC4524A 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 SC4524A is programmable up to 2MHz, allowing the use of small inductors and ceramic capacitors for miniaturization, and high input/ output conversion ratio. The SC4524A is suitable for next generation XDSL modems, high-definition TVs and various point of load applications. Peak current-mode PWM control employed in the SC4524A achieves fast transient response with simple loop pensation. Cycle-by-cycle current limiting and hiccup...
