Product Introduction

Overview

The LP8867C-Q1 is a highly integrated, low-EMI LED driver designed for automotive applications, particularly for backlighting in infotainment systems, instrument clusters, smart mirrors, and heads-up displays (HUD). This device, produced by Texas Instruments, features a DC-DC converter that supports both boost and SEPIC modes, making it versatile for various LED string configurations. It includes 4 high-precision current sinks, each capable of driving up to 120 mA of LED current. The device is AEC-Q100 qualified, ensuring it meets stringent automotive standards, and operates over a wide temperature range from -40°C to +125°C.
