AS1123-BQFT is an advanced LED driver that has several advantages over traditional solutions. This device, with its integrated flyback transformer, operates in a low "drop out" mode, that is, no separate transformer is required. It provides very high efficiency, low ripple, and fast response time. This LED driver is unique in its ability to accurately regulate the output current of the LED string using a constant voltage feedback loop.

AS1123-BQFT uses the flyback topology, which is the most efficient choice for ac-to-dc power conversions. It is designed to allow for a high switching frequency of up to 1MHz and an adjustable output current enabling it to drive currents up to 1A. Output voltage of this device can range from below 1V up to 16V in order to drive various types of LEDs, making it a true universal LED driver.

The AS1123-BQFT includes an internal flyback transformer, which allows for a very high efficiency operation. It is also an isolated LED driver, which means that the signal is not affected by grounding differences and is also safer by providing a secure signal. The device is also capable of providing pulse-width modulation (PWM) in order to dim the LED, which can provide a flicker-free dimming.

The AS1123-BQFT LED driver utilizes a constant voltage feedback loop to accurately regulate the output current at the LED string, providing a more stable output current than traditional drivers. This ensures that the LED operates within its recommended values and does not overshoot the optimal current. With its current-limited design, the device can maintain constant current under varying voltage conditions. This allows for a more reliable operation of the LED display.

Some of the other features of this LED driver include over-voltage protection, short-circuit protection, and internal thermal protection. The device also includes built-in input/output surge protection. This helps in protecting against high voltage transients, over-voltage conditions, or any other unexpected event. The device also has a typical LED On-Off time of 5μs. It can also operate up to 95% efficiency making it an ideal choice for energy saving applications.

In conclusion, AS1123-BQFT is a unique LED driver, which is capable of accurately regulating the output current of the LED string. It is capable of operating at a high switching frequency and its current limited design provides a more reliable operation for LEDs. It has an excellent efficiency of up to 95% as well as many safety features such as over-voltage, short-circuit, and thermal protection. This makes it a great choice for applications ranging from general lighting to outdoor display lighting.
