LP8867CQPWPRQ1 is a highly integrated, low EMI, easy-to-use automotive LED driver with a DC/DC converter. The DC/DC converter supports boost and SEPIC operating modes.

LP8867CQPWPRQ1 features four or three high-precision sink currents, which can be combined to achieve higher current capability.

LP8867CQPWPRQ1 – DC/DC converter provides adaptive output voltage control based on LED forward voltage. This feature regulates voltage to the minimum level required under all conditions, thereby minimising power consumption.

LP8867CQPWPRQ1 – To reduce EMI, the DC-DC converter supports spread spectrum modulation for switching frequencies and enables external synchronisation via a dedicated pin. With its wide adjustable frequency range, the LP8867CQPWPRQ1 avoids interference in sensitive frequency bands.

LP8867CQPWPRQ1 operates from 4.5V to 40V input, supporting automotive start/stop and load dump conditions. It incorporates comprehensive fault detection features.
