LED drivers are components that are specifically designed to power LED light sources. They are more than just simple resistors, as they provide a maximum current and thus optimize LED performance. LED drivers come in two different types, isolated and non-isolated LED drivers. The AS1104-T is a type of non-isolated LED driver.

The AS1104-T is a two-channel LED driver for lighting in a variety of applications, including automotive, industrial and office lighting. It is a low power, low cost driver feature multiple dimming sources, low EMI and no audible noise. It has a wide range of input voltage (2.7V to 17V) and is capable of driving two channels of LEDs with a peak current of 3A/channel.

The AS1104-T features a buck-boost architecture that allows it to operate in either voltage source or current source mode. In voltage source mode, the AS1104-T delivers a dynamic output current to the LEDs that is proportional to the pulse width modulation (PWM) duty cycle. The output current can be modulated in 1mA steps up to the device’s maximum output current of 3A.

In current source mode, the AS1104-T delivers a fixed output current, also referred to as constant current mode. This feature allows the user to maintain a steady, consistent output current even as the supply voltage changes. The output current in this mode is adjustable and can be programmed to the desired level via external resistors.

The AS1104-T also includes a variety of protection features such as over voltage protection, under voltage protection, over temperature protection, short circuit protection, and over load protection. These features ensure that the device is safe and reliable, even under extreme operating conditions.

The AS1104-T is a highly versatile LED driver and can be used in a wide range of applications, including automotive lighting, industrial lighting, office lighting, and LED displays. It is suitable for use with both white and color LED devices, and provides superior performance, efficiency and reliability. Due to its wide range of features, the AS1104-T is a popular choice for LED lighting solutions.
