PMIC - LED Drivers are widely used in various applications, and AP3008KTR-E1 is a successful example of this type of device. It is a step-up LED driver, which is optimized and developed based on AMIC\'s market-leading technology, and is capable of providing wider dimming range and higher efficiency to white LED applications. This article is about the application field and the working principle of the AP3008KTR-E1.

Overview

The AP3008KTR-E1 LED driver is housed in a 8-pin SOT23 package and has an output voltage range up to 20.5V and an adjustable frequency range of 100 KHz to 600 KHz. It features a simple two-wire serial control scheme that can dim the LED output current from 0.05 mA to 18 mA. Furthermore, it allows for 4 different operating modes, PWM mode, pulse-width modulation (PWM) mode, bursting mode and constant off mode. In addition, this device has a unique VDD voltage loss protection function which ensures LED protection when the LED current is too large. Moreover, AP3008KTR-E1 includes a unique current-sharing function, which can enable more than one AP3008KTR-E1 to share the same current required by the LEDs.

Application Fields

The AP3008KTR-E1 LED driver has a wide range of applications. It is ideal for lighting applications, such as backlighting for LCDs and LEDs. It is also suitable for automotive, medical, signage and stage lighting applications. In addition, due to its wide dimming range and capability of current-sharing, it can also be used for 3D display backlighting and LCD TV backlighting. It can help reduce manufacturing costs and space. Furthermore, the AP3008KTR-E1 is certified compliant with UL and CEC standard.

Working Principle

The working principle of the AP3008KTR-E1 is based on a step-up topology. The device has two external pins, VDD and Control pin, and one internal pin, the Current Sense pin. When VDD is connected to a power source, the control pin is used to control the output current of the device. It can be used to PWM, burst, or constrain the output current from 0.05 mA to 18 mA. The Current Sense pin ensures LED protection by sensing the LED current. If the LED current is too large, the device will shut down.

The AP3008KTR-E1 includes several internal protection functions that can protect the device in case of excessive switching operation, such as under-voltage protection, over-voltage protection, over-temperature protection, VDD voltage loss protection and current sense protection. These are necessary to protect the device and the LED from damage.

Conclusion

The AP3008KTR-E1 LED driver is a high-performance and advanced LED driver, which is capable of providing high efficiency, wide dimming range, current-sharing and flexible operation modes. It is suitable for home, medical, automotive and stage lighting applications. Moreover, its integrated protection and safety functions ensure top protection for the device and the LED.
