The Texas Instruments LP8866SQDCPRQ1 is a high-efficiency, automotive-qualified LED driver designed for backlight applications. It integrates a boost controller with six high-precision current sinks, each capable of delivering up to 150mA DC current with typical 1% current matching.
The device operates over an input voltage range of 3V to 48V and features adaptive output voltage control to minimize power consumption. It supports various dimming methods, including 12-bit analog dimming and up to 16-bit resolution via I2C or PWM input, with a dimming ratio of 32,000:1 at a 152Hz PWM frequency. The switching frequency is adjustable from 100kHz to 2.2MHz, with spread spectrum options to reduce EMI.
Designed for automotive applications like infotainment systems, instrument clusters, and heads-up displays, the LP8866SQDCPRQ1 offers extensive fault diagnostics. It is available in a 38-HTSSOP package and operates within an ambient temperature range of -40°C to +125°C.
Key features include auto-phase shift PWM dimming, boost sync input, and thermal shutdown protection, making it a robust solution for demanding automotive display backlighting.
