The LP8866-Q1 from Texas Instruments is an automotive-grade, high-efficiency LED driver designed for display backlighting applications. It features six high-precision current sinks, each capable of delivering up to 200mA DC current with typical 1% current matching.
The device supports a wide input voltage range of 3V to 48V and includes a boost or SEPIC DC/DC controller. It offers flexible dimming capabilities, including PWM and 12-bit analog dimming, with a high dimming ratio of 32,000:1 and up to 16-bit resolution via I2C or PWM input. The switching frequency is adjustable from 100kHz to 2.2MHz, with spread spectrum options to reduce EMI.
Designed for automotive environments, the LP8866-Q1 is AEC-Q100 qualified, with a temperature grade of -40°C to +125°C. It provides extensive fault diagnostics for reliability. The driver is available in a 38-HTSSOP package and is suitable for applications such as automotive infotainment, instrument clusters, smart mirrors, and heads-up displays.
