LP6491 Description

The LP6491 is a pact, high efficiency, high speed synchronous monolithic step-down switching regulator designed to power 5V USB applications. A precise output voltage and programmable cable drop pensation maintain accurate 5V regulation at the USB socket connected to the end of a long cable. Forced continuous operation allows the LP6491 to sink current, further enhancing accurate 5V regulation during load transients.
