Nowadays, using LED backlighting for a wide range of displays to reduce backlight power dissipation is a growing industry trend. The LDB-3700 series is a high efficiency DC/DC controller that drives a number of LEDs connected in a series/parallel configuration. With an internal Pulse Width Modulation (PWM) signal for the dimming control function allows users to set LED brightness smoothly. The LDB-3700 series also features a fast LED current rise/fall time to achieve a wide dimming range and minimizes LED color distortion during the dimming mode and power protection feature enables to protect LED module from damage by over current or over voltage. |
