LP6490 Datasheet | Lowpowersemi

Preliminary Datasheet LP6490 180KHz, 3.5A Step-down Converter With Cable Dropout pensation General Description The LP6490 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 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,...
