The AS3823 TQFP32 DB packaged Integrated Circuit (IC) from Diodes Incorporated is the perfect tool for adding the functionality of an electronic design. It is a low-cost, low power, low voltage, variable frequency control pulse width modulator (VFC-PWM) specifically designed for LED lighting applications. The AS3823 TQFP32 DB’s flexible system solution is a great choice for rapid prototyping and evaluation of various automotive, industrial, and lighting products.

AS3823 TQFP32 DB is a highly integrated and compact driver that offers several advantages over standard driver solutions. It reduces the number of external components and simplifies the design process. The integrated current-mode PWM controller and dimmable LED outputs provide a highly efficient and reliable LED driver solution. Additionally, the LED outputs can be regulated with a wide input voltage range of 17.2 to 27.2V.

The AS3823 TQFP32 DB is capable of driving multiple LED strings in parallel or in series through its three sets of current-mode PWM outputs. Each output is capable of delivering an adjustable 100mA of current from 17.2V up to 27.2V. The circuit’s wide dimming range of 0.2 to 100% is enabled through an adjustment of the output current or through applying to an external PWM signal. When driving multiple LED strings, the circuit can be tuned to match the load impedance with an adjustable current-mode flash controller, the circuit can also be tuned to compensate for voltage droop.

To make the design process more efficient and flexible, the AS3823 TQFP32 DB also integrates several other integrated components. These components include compensation and soft start, a VBUS-CAN Power On/Off control, and an integrated temperature sensor. With these components, the AS3823 TQFP32 DB is a very versatile LED driver capable of providing a wide range of LED lighting solutions.

The AS3823 TQFP32 DB from Diodes Incorporated is an ideal driver for LED lighting applications. It is a compact, efficient solution for driving multiple LED strings in parallel or in series and provides a wide range of dimming capabilities. With its integrated components and wide input voltage range, the AS3823 TQFP32 DB is a great choice for rapid prototyping and evaluation of various automotive, industrial, and lighting projects.
