(Switching Regulator Type)

BD8112EFV-M

No.11039ECT11

●Description

BD8112EFV-M is a white LED driver with the capability of withstanding high input voltage (36V MAX). This driver has

2ch constant-current drivers integrated in 1-chip, which each channel can draw up to 150mA 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 voltage input and also to remove the constraint of the number of LEDs in series connection.

The brightness can be controlled by either PWM or VDAC techniques.

●Features

1) Input voltage range 5.0 -30 V

2) Integrated buck-boost current-mode DC/DC controller

3) Two integrated LED current driver channels (150 mA max. each channel)

4) PWM Light Modulation (Minimum Pulse Width 25µs)

5) Oscillation frequency accuracy ±5%

6) Built-in protection functions (UVLO, OVP, TSD, OCP, SCP)

7) LED abnormal status detection function (OPEN/ SHORT)

8) HTSSOP-B24 package

●Applications

Backlight for display audio, small type panels, etc.

●Absolute maximum ratings (Ta=25℃)
