LED6001 Datasheet PDF - STMicroelectronics

Description
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.
