PWM-dimmable single channel LED driver with integrated boost controller
The LED6001 device is a LED driver that combines a boost controller and a high-side current sensing circuitry optimized for driving one string of high-brightness LEDs. The device is compatible with multiple topologies such as boost, SEPIC and floating load buck-boost. The brightness of the LEDs can be controlled through PWM dimming and analog dimming (10:1 ratio) by means of two independent pins. Enhanced PWM dimming can be obtained thanks to a MOSFET in series with the LED string and directly driven by a dedicated pin.
The high-side current sensing, in combination with a P-channel MOSFET, provides an effective protection in case the positive terminal of the LED string is shorted to ground. The high precision current sensing circuitry allows a LED current regulation reference within ± 4% accuracy over the whole temperature range and production spread.
A fault output (open-drain) informs the host system about faulty conditions: device overtemperature, output overvoltage (disconnected LED string) and LED overcurrent.
