PMIC – LED Drivers

IR2E49U6 is an LED driver designed for various applications such as lighting, camera, dashboards, and so on. It can be used for multiple power components, and the integrated multi-level voltage control (MVC) feature allows auto-detection as well as voltage setting for three channel power inputs. The power-supply controller can regulate the power inside the system, while the PWM backlight dimming control provides a brightness control solution.

Application Field of IR2E49U6

The IR2E49U6 is suitable for application in multiple fields, such as:

• Lighting – The driver can be used to control the brightness of solid-state lighting such as LED.
• Camera – The driver can be used to control the brightness on camera as well.
• Dashboard – The driver can also be used for monitoring system and display messages on the dashboard.

Because the IR2E49U6 is a multiple power component-controlled LED driver, the usage of the component is not just limited to the above mentioned applications, and can also be used for other types of application.

Working Principle of IR2E49U6

The IR2E49U6 uses a multi-level voltage control (MVC) feature to auto-detect and regulate the power supply to the component. This is done via the power-supply control feature, which is able to use different control methods such as average current limitation or peak current limitation to adjust the power levels inside the component. The component also comes with a PWM backlight dimming control, which is used to control the brightness of the LED and regulate the intensity level of the light.

The component also has an embedded flash memory, which can be used to store firmware and save setting configurations among different applications. In addition, it has a low-noise clock oscillator and can operate at frequencies up to 60MHz.
