The LP8556SQE-E08 from Texas Instruments is a high-efficiency DC/DC boost converter designed as an LED backlight driver. It offers 6 configurable channels, each capable of delivering up to 50 mA of current.
Key electrical specifications include an input voltage range of 2.7V to 36V (supporting multi-cell Li-Ion batteries) and an output voltage range of 7V to 43V. The device features integrated 0.19-Ohm power MOSFETs and supports switching frequencies of 312 kHz, 625 kHz, and 1250 kHz. Brightness control is managed via PWM and/or I2C interfaces. The driver includes adaptive dimming for optical efficiency and phase-shift PWM mode to reduce audible noise.
For reliability and performance, the LP8556SQE-E08 incorporates programmable edge-rate control and spread spectrum schemes to minimize switching noise and improve EMI. It also provides comprehensive protection features including LED fault detection (short and open), UVLO, TSD, OCP, and OVP.
Available in compact DSBGA (20-pin, 3.96 mm²) and WQFN (24-pin, 16 mm²) packages, this LED driver is suitable for surface mount applications. The operating temperature range is -30°C to 85°C.
