Preliminary Datasheet LP6490 180KHz, 3.5A Step-down Converter With Cable Dropout Compensation General Description The LP6490 is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator designed to power 5V USB applications. A precise output voltage and programmable cable drop compensation maintain accurate 5V regulation at the USB socket connected to the end of a long cable. Forced continuous operation allows the LP6490 to sink current, further enhancing accurate 5V regulation during load transients.
