LP5811DDRRR TI LED Drivers
The LP5811DDRRR is a synchronous boost 4-channel RGBW LED driver from Texas Instruments, featuring the same core functionality as the LP5811DYBHR in an alternate thermally enhanced package. It operates over an input voltage range of 0.5V to 5.5V and features ultra-low normal operation current of 0.4 mA typical. The integrated synchronous boost converter maintains excellent efficiency across a wide input range, with adjustable output voltage from 3V to 5.5V. The device supports both analog and PWM dimming with 256 steps per channel. Housed in a 12-pin WSON (DRR) package (3mm x 3mm) with an exposed thermal pad for enhanced thermal dissipation, it operates over -40°C to 85°C. Applications include battery-powered LED lighting, portable electronics, smart speakers, and industrial control panels. In stock at HL Electronics – request a quote for fast delivery.
