LED1642GWQTR Integrated Circuits (ICs)

PMIC - LED Drivers

The LED1642GWQTR is a PMIC - LED Driver intended for a wide range of applications. It provides control of illumination level and brightness based on its unique input/output architecture, which allows for customizing the output via external controls.

Application Field

This PMIC - LED Driver is suitable for applications such as automotive, medical, industrial and consumer lighting, indoor and outdoor illumination, sign and display illumination, decorative lighting, and more.

As it provides high reliability, the LED1642GWQTR is capable of working in environments that require high durability and a long-term performance. It has an IP67 rating for dust and water resistance, so it can be used in a variety of circumstances, such as light locations with high levels of dust and moisture.

In addition, the device is designed to operate in a wide temperature range from -40 ℃ to +110 ℃,so it can handle extreme operating conditions.

Working Principle

The LED1642GWQTR works with pulse width modulation (PWM) to provide dimming and brightness control. The device consists of two ICs: the LED driver and a control circuit. The LED driver controls the output current of the LEDs, while the control circuit takes in 0-10V input signals, controls the output current via a built-in DC/DC converter, and then drives the LED driver so that the LED’s brightness can be accurately controlled.

The LED driver is a high-efficiency synchronous buck converter that takes the input voltage and converts it into the desired output voltage to drive the LEDs. It also has temperature compensation and over temperature protection features to ensure the further safety of the device.

The control IC integrates voltage, PWM dimming, green and blue white LED dimming, and other functions into a single chip. It is capable of generating linear analog voltages for dimming or digital signals for on/off and other control functions, allowing for higher level customization.

Conclusion

The LED1642GWQTR is a PMIC - LED Driver designed for a wide range of applications with its IP67 dust and water resistance rating, operating temperature range of -40 ℃ to +110 ℃, and its unique input/output architecture. It is also capable of providing dimming and brightness control via a synchronous buck converter, along with temperature compensation and over-temperature protection features, to ensure the device’s performance and durability.
