Constant-current LED driver IC with PWM control

The A6280 from Allegro MicroSystems Europe is a new 3-bit constant current LED driver which enables users to minimise the number of components needed to drive LEDs with large pixel spacing. The new driver controls LED luminance using a pulse width modulation (PWM) scheme which gives the application the capability of displaying up to one billion colours. An external resistor is used to set the overall maximum current, which can be set over a wide ...
