There is a strong demand for components, such as the AT9917TS-G, that cohesively create and maintain efficient lighting systems. Although primarily intended for LED’s, the AT9917TS-G is also applicable for other semiconductor applications as it serves as a power management IC. The device is capable of driving up to 3 channels of LEDs, allowing it to be implemented in various types of lighting and display systems. This article will discuss the application field and underlying working principles of the AT9917TS-G.

The AT9917TS-G is a single stage switching power supply and can be used to construct power supplies ranging from 5V to 60V. It features low input, high efficiency, and low output ripple voltage. The AT9917TS-G also incorporates a number of other features, such as high-efficiency, low shutdown current, adjustable peak current and dimming control, over-voltage protection, overtemperature protection, and a timer. These features make the AT9917TS-G the ideal choice for powering LED’s.

LED drivers are special type of power supplies that convert high-voltage AC input into a low voltage DC output. The primary purpose of a LED driver is to maintain a constant voltage and/or current to the LED. Without a LED driver, the LED’s would be operating at an unstable voltage, causing dimming and flickering or even damaging the LED’s. The AT9917TS-G is capable of not only supplying LED’s with a constant current, but also the adjustable electronic dimming.

The AT9917TS-G provides three outputs for driving LED’s. The device contains a fixed frequency, PWM controlled, buck converter and two channels of constant current buck converters. The PWM output is designed for dimming control, while the other two outputs provide constant current for the LED’s.

The AT9917TS-G can also be configured to provide constant current which can be programmed from 350mA to 1650mA with an external resistor. The output current can be adjusted using the dimming port to allow the current to increase or decrease depending on the dimming level.

The AT9917TS-G also provides over-voltage protection and overtemperature protection. The device detects if the output voltage exceeds the maximum level of the LED’s or if the temperature exceeds the specified limit, in which case the power to the LED is stopped to prevent damage to the LED’s.

In addition, the AT9917TS-G includes a timer that prevents the output current from being too low at the beginning and end of the dimming process. This timer can be used to provide a more stable current when dimming the LED’s and prevents damage to the LED’s during dimming.

The AT9917TS-G is therefore ideal for driving LED’s in a variety of lighting and display applications. It is capable of providing a constant current that has been proven to be reliable and efficient. It also includes various protection features such as over-voltage and overtemperature protection, as well as a timer to prevent LED damage during dimming. All of these features make the AT9917TS-G the ideal choice for powering LED’s in a variety of lighting and display systems.
