The IS31LT3360-SDLS3-EBAIC is a three-channel, low-power, DC-DC, constant-current LED driver utilizing a charge-pump boost controller, a standard current ABC control structure and a power P-MOSFET switch. This driver IC is most often used to drive LED display boards, as it is an excellent way of delivering uniform current for a given array of LEDs. It is also used in many other display applications, including billboards and highway signs.

The IS31LT3360-SDLS3-EBAIC is designed to work with a wide variety of LED packages and supporting components. It supports LED packages with a forward current up to 350mA, which can be adjusted with a single external resistor. The IC is also equipped with a short-circuit protection function to protect the LEDs from any sudden over-current conditions. Additionally, the EBAIC also provides OVP (over-voltage protection) and open-LED protection to ensure a safe operation.

The work principle of the IS31LT3360-SDLS3-EBAIC is based on the inductor-capacitor (LC) charge-pump principle. It consists of three main blocks – the ABC, the switch and thecharge pump controller. The ABC block handles the regulation of the LED current, using a set of interconnected resistors to set the current for the LEDs. The switch then takes the regulated current and uses a low-voltage P-MOSFET switch tocomplement the current loop. Finally, the charge pump controller takes the output from theswitch and boosts the voltage as needed to ensure proper current performance for the LEDs.

In terms of application field, the IS31LT3360-SDLS3-EBAIC is widely used in many different types of LED displays, including back-lighting, billboard displays, traffic signs and vehicle lighting. Additionally, the driver IC is also suitable for driving general lighting sources such as residential lighting, industrial lighting and commercial lighting. In each application field, the IS31LT3360-SDLS3-EBAIC offers a low quiescent current, a wide operating temperature range, a low BOM cost and an excellent level of performance.

In short, the IS31LT3360-SDLS3-EBAIC is an excellent choice for LED display applications. Its combination of a low quiescent current, a wide operating temperature range, a low BOM cost and a powerful performance make it ideal for many different types of LED applications. Furthermore, the advance protection features provide the user with a reliable, secure and safe operation.
