Description
The HM1485 is a synchronous step down regulator with CC control from a high voltage input supply. Operating with an input voltage range of 8V ～ 30V, the HM1485 achieves 4.5A continuous output current with excellent load and line regulation. The switching frequency is programmable from 130KHz to 500KHz and the synchronous architecture provides for highly efficient designs. Current mode operation provides fast transient response and eases loop stabilization.
The HM1485 requires a minimum number of readily available standard external components. Other features include cable compensation, programmable current limit and thermal shutdown.
The HM1485 converters are available in the industry standard SOP8-PP packages.
