The Texas Instruments LP8556SQE-E08/NOPB is a high-efficiency DC/DC boost converter designed for LED backlight applications. This device 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 and an output voltage range of 7V to 43V. It supports 3 to 12 LEDs in series per channel. The driver features I2C and PWM brightness control, with a phase-shift PWM mode for reduced audible noise and adaptive dimming for optical efficiency. Multiple switching frequencies are available, including 312 kHz, 625 kHz, and 1250 kHz, along with programmable edge-rate control and spread spectrum for minimized switching noise and improved EMI performance.
Protection features include LED fault detection (short and open), UVLO, TSD, OCP, and OVP. The integrated 0.19-Ω power MOSFET contributes to its high efficiency, reaching up to 95% peak efficiency.
The LP8556SQE-E08/NOPB is available in a 24-WQFN (4x4) package, suitable for surface mounting.
