General Description

The LP6493 is a synchronous step down regulator with CC control from a high voltage input supply. Operating with an input voltage 8V~30V, the LP6493 achieves 3.5A continuous output current with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. The LP6493 requires a minimum number of readily available standard external components. Other features include cable compensation, programmable current limit and thermal shutdown. The LP6493 converters are available in the industry standard SOP8 packages.
