Designed to provide constant-current drive for white-LED backlights in medium-to-large-format automotive TFT-LCD displays, the dual-channel BD8113EFV-E2 white-LED driver IC is capable of up to 150-mA constant current per channel with current-mode buck/boost dc/dc control. The buck/boost configuration also frees up the restriction on the number of LEDs that can be connected in series.
Additional features include a maximum input voltage of 36 V (supply voltage range: 5 to 30 V) and an operating temperature range from –40° to 105°C. The part also includes undervoltage lockout, overvoltage protection, thermal shutdown, overcurrent protection, and short-circuit protection. Inputs are provided for brightness modulation via PWM or VDAC control. ($5 — samples available now.)
