It is an easy-to-use board that is ideal for quickly understanding features, verifying chip functions, and quickly demonstrating system solutions. Allegro is dedicated to providing solutions for LED lighting solutions and the high quality standard of its integrated circuits are recognized worldwide. With the help of this evaluation board, engineers can quickly verify the features of the A6210 and develop a qualified LED lighting solution.

Features of DC336A

The DC336A features a 2-phase constant current buck driver with Allegro A6210, which can drive up to 4 LEDs in series with a wide input voltage range from 4.5V to 24V and an adjustable output current from 10mA to 2000mA. It also has two additional pins for setting output current with external voltage. The DC336A houses an additional A5902 high side linear driver that supports up to 10mA with 250mV dropout voltage, ideal for adding further LED strings in series. It also has some common electrical safety features such as LED open and LED shortcircuit protection and over temperature protection.

Application fields

DC336A boards are designed for evaluating the performance and features of the A6210 LED driver integrated circuit. It is suitable for applications such as general area lighting, advertisement signs, and indoor commercial lighting. It is also applicable for automotive driving lights, such as daytime running lights, fog lights, and headlights. With the additional A5902 high side linear driver, powering two LEDs in series is possible for special lighting applications such as reading lamps and foot lights.

Working Principles

DC336A boards use the constant current buck driver of A6210 and the high side linear driver of A5902 to provide a complete LED lighting evaluation solution.The A6210 is a complete 2-phase constant current buck driver capable of driving up to 4 LEDs in series with a wide input voltage range from 4.5V to 24V and adjustable output current of 10mA to 2000mA. Through two additional pins it also achieves external, grove-adjustable output current. The A6210\'s adjustable, constant current performance ensures the LEDs are always driven with the proper amount of current and it is stable under variations of input voltage or temperature. The A6210 also includes a slew rate limiting, over temperature protection and essential safety features such as LED open/short circuit protection.The A5902 is a 250 mV dropout high side linear driver capable of driving up to 10mA of current. It is designed to control the brightness of two LEDs in series, making it ideal for special lighting applications such as reading lights, foot lights and spot lights.The A6210 and the A5902 can be used together to expand the LED current and support various lighting applications.
