Preliminary Datasheet LP6491
180KHz, 5A Step-down Converter With Cable Dropout Compensation
General Description
The LP6491 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 LP6491 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, all...
