The LP8556SQ-E09/NOPB from Texas Instruments is a high-efficiency DC/DC boost converter designed for LED backlight applications. This device features 6 configurable channels, each capable of delivering up to 50 mA of current. It supports a wide input voltage range from 2.7V to 36V, making it suitable for multi-cell Li-Ion battery applications, with an output voltage range of 7V to 43V.
Key features include I2C and PWM brightness control, phase-shift PWM mode for reduced audible noise, and adaptive dimming for enhanced optical efficiency. The driver also incorporates programmable edge-rate control and spread spectrum schemes to minimize switching noise and improve EMI performance. Integrated protection features include LED fault detection (short and open), UVLO, TSD, OCP, and OVP.
The LP8556SQ-E09/NOPB is available in a 24-pin WQFN package with an exposed pad, measuring 4mm x 4mm, and is designed for surface mount applications. Its operating temperature range is -30°C to 85°C (TA). The device offers multiple switching frequency options, including 312 kHz, 625 kHz, and 1250 kHz, and includes an integrated 0.19-Ohm power MOSFET.
