The MAX1553ETA+T is a high-performance AC-output LED driver developed by Maxim Integrated. It provides efficient, compact and cost-effective solutions for driving AC LED strings, such as general lighting systems, automotive lighting, and LCD backlighting. This LED driver allows a smaller design footprint and increased design flexibility as it offers adjustable current regulation and multiple dimming controls to support a range of LED power levels.

The MAX1553ETA+T LED driver uses two distinct components in its design: the controller and the transistor. The controller contains an LED driver operating at a fixed frequency, typically 16 kHz. This frequency allows the LED driver to operate in both AC and DC applications without significant noise issues. The controller also features an adjustable current limit, adjustable voltage output, and overvoltage protection.

The transistor is an MOSFET switch combined with a sense resistor, allowing for accurate control of the current through the LEDs. When the sense resistor senses a voltage drop across the LEDs due to their resistance, the transistor is triggered to turn off, thereby controlling the current.

The MAX1553ETA+T LED driver operates by controlling the voltage applied to the string of LEDs. The voltage applied is set by the controller and is typically either low-voltage or AC. With AC operation, the LED driver regulates the current through the LEDs by turning them off at the peak of the waveform, allowing the current to efficiently regulate itself. With low-voltage operation, the LED driver uses a low-voltage supply, a sense resistor and the MOSFET switch to regulate the current through the LEDs.

In addition to its current regulation, the MAX1553ETA+T LED driver includes dimming controls to adjust the output current. The LED driver includes both digital and analog dimming controls, which allow the brightness of the LEDs to be adjusted according to the user’s application. Digital dimming allows the user to set a maximum brightness level and then adjust the brightness according to a user-defined step. Analog dimming allows the user to continuously adjust the brightness of the LEDs by changing the voltage applied to the LEDs.

The MAX1553ETA+T LED driver provides a reliable and efficient solution for driving AC LED strings. Its adjustable current limit and multiple dimming controls provide a flexible design with a smaller design footprint. Its small size and flexible design also make it ideal for applications such as general lighting, automotive lighting, and LCD backlighting. It’s a great solution for any application that requires efficient and reliable LED performance.
