AX2061-1-WD1

PMIC - LED Drivers are essential components in various electronic devices, especially those that use LED lights. The AX2061-1-WD1 is a type of PMIC - LED Driver, which specializes in controlling and providing power to LED lighting efficiently and reliably. This article will discuss the application field and working principle of the AX2061-1-WD1.

The AX2061-1-WD1 is specifically designed to drive and dim any single color LED lighting installations. Due to its feature of low extra current loss, it is applied widely in display backlight systems such as mobile phones, laptop computers, and digital cameras. It is also used in high power LEDs lighting, automotive lighting, and industrial lighting applications. The device provides dimming function for LED lightings with extremely high linearity and minimal power loss.

The working principle of the AX2061-1-WD1 mainly involves two aspects - power control and dimming. On the power control part, the device provides a constant PWM voltage for the LED. It compares the current cycle period and the external reference voltage to generate a PWM level on the power side. This PWM level is then adjusted to control the LED light output. On the dimming part, the device adjusts the external control voltage to change the light output. Through a comparator circuit, the PWM signal is also affected.

The AX2061-1-WD1 provides two different voltage levels to guarantee a stable current supply, which is the constant voltage of 1.2V and the constant current of 20mA. When the input voltage is lower than 2.5V, it will automatically switch to the constant current mode, which avoids over-voltage, over-current and short circuit. To ensure maximum light efficiency, the device utilizes integrated IC technology to compare several reference voltages, and this is also used to modulate the PWM signal.

Due to its efficient power management, the AX2061-1-WD1 is especially suitable for applications with two power sources or constant power consumption. This allows it to be used in various situations such as when power consumption needs to be reduced or if there is an unpredictable power supply. Furthermore, due to its integrated circuit design, it has a wide operating temperature range and does not require special tools for installation.

To summarize, the AX2061-1-WD1 is a PMIC-LED Driver designed for high efficiency power regulation and dimming of LED lights. It can provide constant PWM voltage to the LED, and make use of the integrated IC structure to regulate the power supply and adjust the light output. Furthermore, it has low extra current loss and possesses a wide operating temperature range. Therefore, it is applicable for various LED lighting systems such as mobile phones, laptops, and digital cameras, as well as for high power LED lighting and automotive lighting.
