LED Backlit Industrial Displays
Atmel® LED dDrivers offer solutions for iIndustrial dDisplays. An integrated DC DC-to to-DC power supply controller and internal current sinks reduce component count, provide design flexibility and offer lowest overall system solution cost. These advanced devices also offer a digital control loop, which means they require no external components to manage the LED supply and regulate LED current up to 30mA per LED string with up to 12 LEDs per string. LED dimming is achieved through an external PWM signal or an internal 8-bit PWM engine. Analog dimming of LED string current is available for use with an ambient light sensor (ALS) and/or temperature management with a thermistor or IC temperature sensor.
