Le LP8861QPWPRQ1 device is an automotive high-efficiency LED driver with an integrated boost/SEPIC converter. The device features low EMI and is very easy to use.
The boost/SEPIC converter provides adaptive output voltage control based on LED current sink headroom voltage. This feature regulates the voltage to the lowest level required under all conditions.
With a wide adjustable frequency range, the LP8861QPWPRQ1 device is able to avoid interference in the amplitude modulated (AM) radio frequency band.
The LP8861QPWPRQ1 device can optionally drive an external p-FET to disconnect the input supply from the system in the event of a fault. This reduces inrush current and reduces standby power consumption.
