LED drivers are commonplace in modern day applications, from street lighting to aircraft signaling, giving quick and accurate response when providing power to a whole array of different types of LEDs. In addition to this, they offer high efficiency, extended control and the ability to interface with many other control electronics, all of which are necessary in any power-hungry application. The Linear Technology LT3498EDDB is a PMIC (Power Management Integrated Circuit) specifically tailored to meet the demands of LED driver applications.

The LT3498EDDB is designed to drive up to 9 low-power LEDs as an independent channel, and as much as 81 low-power LEDs in cascaded configurations. It also provides a single analog input that controls the entire cluster of LEDs. With integrated dimming and adjustable brightness capabilities, the LT3498EDDB is easy to use and can be tailored to produce varying levels of lighting output.

The LT3498EDDB comes in a 15-pin QFN package, combining a low-voltage (1.8V to 5.25V) boost LED matrix and high-voltage buck LED matrix circuits into a single integrated device. Additionally, the device features an analog dimming control with a depth-of-modulation of greater than 90%. This provides for better brightness control in LED applications which require slow dimming, such as in street lighting, or where varying light levels are needed.

A key feature of the LT3498EDDB is its built-in power management controls, which extend the driving current to the LEDs while protecting them from Junction Over-Voltage (JOV). This helps to ensure longer life and reliability of the device-powered LEDs. Furthermore, the device includes over-voltage protection, preventing device from damaging due to excessive input voltage.

The LT3498EDDB offers low quiescent current operation and low output ripple, providing an efficient and precise driving solution for modern LED applications. Additionally its adjustable Sleep Mode (SLP mode) allows the user to switch rapidly between drive and sleep operations, which reduces power consumption while still providing outstanding lighting performance. This makes the LT3498EDDB a desirable choice for applications that require regularly controlled on/off operations and LED dimming.

In terms of applications, the LT3498EDDB PMIC LED driver is ideally suited for a wide selection of LED lighting requirements, such as those found in street lighting systems, automotive headlights, indicator lights and instrument displays. Furthermore, this device offers excellent integration, along with support for various control electronics, making it an extremely versatile solution for a range of different applications.
