General Description

BD81A04EFV-M is a white LED driver with the capability of withstanding high input voltage (40V MAX).This driver has 4ch constant-current drivers integrated in 1-chip, which each channel can draw up to 120mA max, so that high brightness LED driving can be realized.

Furthermore, a current-mode buck-boost DC/DC controller is also integrated to achieve stable operation against unstable car-battery voltage input and also to remove the constraint of the number of LEDs in series connection.

The brightness can be controlled by PWM techniques.

Key Features

  • ed buck-boost current-mode DC/DC controller.
  • Four integrated LED current driver channels (120 mA max. each channel).
  • PWM Light Modulation.
  • Built-in protection functions (UVLO, OVP, TSD, OCP, SCP).
  • Abnormal status detection function (OPEN/ SHORT).
