ALED6001 Description
The ALED6001 is an automotive-grade (AECQ100 pliant) LED driver that bines a boost controller and high-side current sensing circuitry optimized for driving one string of highbrightness LEDs. The device is patible with multiple topologies such as boost, SEPIC and floating load buck-boost. PWM dimming of the LED brightness is achieved by means of an external MOSFET in series with the LED string and directly driven by...
