Overview
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.
Accurate and programmable input/output current limit, an input current monitor pin and an output current monitor pin improve system reliability and safety, allow the user to implement latch-off or auto-retry functionality and can eliminate the need for a USB switch IC.
Dual feedback allows regulation on the output of a USB switch, protecting USB devices during fault conditions.
Thermal shutdown provides additional protection by limiting power dissipatio...
