Description

The HX1254A-AGN is a asynchronous step down regulator from a high voltage input supply. HX1254A-AGN achieves 1.5A continuous output current with excellent load and line regulation in input operation voltage. The switching frequency is programmable and the asynchronous architecture provides for highly efficient designs. Current mode operation provides fast transient response and eases loop stabilization.

The HX1254A-AGN requires a minimum number of readily available standard external components. Other features include cable compensation and thermal shutdown.

The HX1254A-AGN converters are available in the industry standard SOP-8L packages.
