The Texas Instruments LP8556SQX-E09/NOPB is a high-efficiency DC/DC boost converter designed as a 6-channel LED backlight driver. It operates with an input voltage range of 2.7V to 36V and can provide an output voltage range of 7V to 43V. Each channel can deliver up to 50mA of current.
This LED driver supports both PWM and I2C for brightness control, offering flexibility in dimming applications. It includes features like phase-shift PWM mode to reduce audible noise and adaptive dimming for improved optical efficiency. The device also incorporates programmable edge-rate control and spread spectrum to minimize switching noise and enhance EMI performance.
For reliability, the LP8556SQX-E09/NOPB includes LED fault detection for short and open circuits, along with UVLO, TSD, OCP, and OVP protection features. It is available in a 24-pin WQFN package suitable for surface mounting.
Key electrical specifications include a maximum switching frequency of 1250 kHz and a peak efficiency of 95%. The operating temperature range is from -30°C to 85°C.
