Description
The HC8813 is a synchronous step down regulator from a high voltage input supply. Operating with an input voltage range from 10V to 30V, the XHC8813 achieves 2.1A continuous output current with excellent load and line regulation. The switching frequency is programmable from 150 kHz to 500 kHz and the synchronous architecture provides for highly efficient designs. Current mode operation provides fast transient response and eases loop stabilization.
The HC8813 requires a minimum number of readily available standard .
