PMIC - LED Drivers are the most important products for the illumination applications. The LM3410YSDX/NOPB LEDs driver from Texas Instruments is one of them. Here we will discuss the application field and working principle of the LM3410YSDX/NOPB LED driver.

As one of the leading LED Driver from Texas Instruments, the LM3410YSDX/NOPB LED Driver is a high efficiency, flexible charge pump controller for driving multiple strings of LEDs. It can drive up to four parallel LED string. It has PWM Dimming support and the external sense option to maximize the LED driver efficiency. It is suited for applications such as display backlighting, general Illumination, and SSL lighting.

Besides its application, its working principle is also interesting. This LED driver adopts the architecture of a synchronous buck converter, but instead of a switching transistor and diode, the LM3410YSDX/NOPB LED driver uses an array of two charge pump stages to convert the voltage. The two charge pumps increase the maximum output voltage by a factor of two compared to the input voltage. This enables the LM3410YSDX/NOPB LED driver to accept a wide bus voltage range from 3.5V to 28V and have a maximum output voltage up to 80V.

The LM3410YSDX/NOPB LED driver also has several other features that make it a great choice for powering LEDs. The device has a wide input voltage range so it can accommodate a variety of power source configurations. It also has adjustable current limit, allowing for more precise control of the LED current. It is also programmable using either a resistor or PWM. There is also a thermal shutdown feature that allows the LED driver to automatically shut down in the event of an over-temperature condition.

The LM3410YSDX/NOPB LED Driver also includes an input voltage monitor and an undervoltage lockout. The input voltage monitor provides a feedback signal that can be used to control the LED brightness, and the undervoltage lockout prevents the LED driver from operating during periods of low input voltage. Additionally, the LM3410YSDX/NOPB LED Driver has a 12-bit watchdog timer that can be used to reset the device if it becomes unresponsive.

The LM3410YSDX/NOPB LED driver is a flexible, easy to use product that is ideal for applications such as lighting, displays, and consumer electronics. It has an adjustable current limit and is programmable via a resistor or PWM and supports PWM dimming, making it an ideal choice for all types of LED lighting applications. With an input voltage range that spans from 3.5V to 28V, the LM3410YSDX/NOPB LED driver is the perfect solution for a wide variety of LED driving projects.
