PMIC - LED Drivers have seen ever-increasing acceptance in many industries over the last few years, with their ability to increase the efficiency of power delivery and adapt to changing environmental conditions. The AP1690MTR-G1 from Anpei is one of the more advanced LED Drivers on the market today with performance and features that make it a great choice for many applications. This article looks at the application field and working principles of the AP1690MTR-G1.

The AP1690MTR-G1 is a multi-channel, multi-functional LED driver with high voltage and low voltage outputs. It is well suited to operate a wide range of LED applications, such as backlighting, signboards and LCD drivers. It is also capable of supplying fixed currents up to 500mA at output voltages up to 50V. The AP1690MTR-G1 is well equipped to handle the constant and dynamic loading that is common in many LED applications, with intelligent Current Sense switching, Thermal Protection and Fault Tolerance features. These features also make the AP1690MTR-G1 a great choice for applications that require automatic dimming or various output channel combination.

The AP1690MTR-G1 contains a four-pin interface, allowing for the direct connection of LED strings up to 50V. Onboard current sense switching allows for precise LED current mapping, enabling precise control of LED operation. This can improve light quality, maintain efficiency and reduce component power dissipation. The AP1690MTR-G1 can also handle multi-channel current output control, allowing up to three independent LED strings of up to 50V. Additionally, the device has an internal clock which can be used to implement dimming functions and cycle multiple LED channels.

The AP1690MTR-G1 also benefits from a range of additional features; its Fault Tolerance feature will detect open or short LED strings and provide integrated protection. This allows the LED array to continue operating even in the event of LED failure. The AP1690MTR-G1 also contains an integrated thermal protection feature which will limit its operation when the module temperature rises over a certain level. This can avoid possible damage to the LED module in extreme weather or in a poor or malfunctioning environment.

The AP1690MTR-G1 is designed to support many different types of LED lighting applications. It is capable of driving single, dual or multi-channel LED strings up to 50V and 500mA. It is also capable of PWM and analog dimming, enabling dynamic control of the brightness of multiple LED channels. With a low profile and low power consumption, the AP1690MTR-G1 is a great choice for a wide range of applications, including backlighting, lighting control and LCD drivers.

In addition, the AP1690MTR-G1 can also handle a self-protection function; its UVLO protection will protect the module against over-voltage and under-voltage conditions. This protection can prevent the device from operating outside of the reliable parameters and will reduce potential damage to the system.

The AP1690MTR-G1 device has an advanced data transmission process; its SBS-I2C interface allows for direct communication between the driver and the external system. Using this interface, the AP1690MTR-G1 can be connected to display controllers and other control systems, allowing for the easy control of the LED channels. In addition, the AP1690MTR-G1 supports power-off detection, allowing for the detection of low-power or short-circuit conditions and the automatic shutdown of the LED circuits for increased safety.

To sum up, the AP1690MTR-G1 from Anpei is a multi-channel LED driver with low power consumption and good performance. With a range of advanced features, such as thermal protection, current sense switching and fault tolerance; this driver is ideal for many applications, including backlighting, display control, LCD drivers and more. Its SBS-I2C interface makes it easy to connect to other external control systems, allowing for the dynamic configuration of the LED channels and the protection of the device.
