LED backlight driver board

(D27 series)

The D27 series is a high voltage Boost driver with 1~4 channels(option) adjustable constant current regulators for LED backlight applications.one to eight regulated current ports are designed to provide uniform and pure DC constant current sinks for driving LEDs within a large range VF variations. It can drive a number of LEDs in series/parallel configuration.

It could output the lowest dropout voltage among used channels to Boost Driver in order to maintain the output voltage in optimal level. An OVP circuit is built for open-loop protection when any string becomes open.

The built in DC to PWM (Pulse Width Modulation) module signal for the dimming control function allows users to set LED brightness smoothly.

Feature Wide input voltage range. External PWM or DC (0~+5V) dimming control (Built-in the Pulse Width Modulation (PWM) dimming control). External power On/Off control. 70V current sinks breakdown voltage for up to 20 pcs of LEDs in series. Constant output current range: 30mA~120mA per string. OCP/OTP/OVP functions. OVP circuit is built for open-loop protection when any string becomes open. Thermal protection function protects IC from over temperature damage. LED open/short protection. Soft start
