AN295057 - This application note describes recent trends in the electronic component power management industry, in particular an optimized high-brightness LED (HB LED) driver, the Allegro A6210 device, which provides an advanced form of power management.

This application note discusses LED headlights for two-wheelers, passenger vehicles, commercial vehicles, and mild hybrid vehicles, and explores battery voltage and power requirements for the headlights used in these vehicles.

P0240: Using Allegro's LED drivers with integrated noncontact Hall-effect switches instead of mechanical switches can prevent corrosion and improve the reliability of LED systems in RCL applications.

AN296207 - In two-wheeler stop and tail light applications, particularly those that use a Rear Combination Lamp (RCL), OEMs use LEDs instead of incandescent bulbs to ensure longer application life.

This application note discusses the features and application of the Allegro A6271-1 switching LED controller in automotive high-power applications when driving a high number of LEDs.

The proliferation of light-emitting diode (LED) drivers in various automotive applications over the past decade has been driven by a need for efficient lighting and aesthetics.

This article demonstrates the PWM dimming benefits achieved by PEB when compared to the behavior of conventional LED driver control methods.

P0220: This application note presents the implementation of adaptive pre-regulator where output voltage is dynamically adjusted to provide optimum voltage to the LED driver.
