DS3680MX/NOPB, manufactured by Texas Instruments, is a device among PMIC (Power Management Integrated Circuit) family that consists of power distribution switches, load drivers and other integrated circuits. It is suitable for a variety of applications such as LED lighting and automotive applications. This article will discuss its application field, and its working principle.

Application Field

The DS3680MX/NOPB is capable of operating at high currents up to 10A, making it suitable for a wide range of applications. It can be used to drive white, red, green, and blue LEDs. It is suitable for applications that require dimming control or fast stroboscopic flicker, and is optimized for the automotive environment. Its high power handling capabilities make it ideal for applications where a switched capacitor filter is needed, such as in power supplies. It can also be used in applications such as motor controllers and DC motor drivers.

It is specifically designed for automotive environments, and thus is able to withstand high temperatures, making it a great choice for applications where reliability and durability are key. Its low quiescent current draws means that it is highly energy efficient, making it a great choice for those looking for an efficient system.

Working Principle

The DS3680MX/NOPB works by utilizing a switched capacitor filter to regulate current flow through a load. This allows it to switch from an on state to an off state much more quickly than a traditional linear regulator. It can do this quickly by using the voltage across its output capacitor, which is regulated by a feedback loop. The device also uses a slew rate limiting circuit to ensure that the transition is safe for the load.

The device is designed to work with a variety of power sources, including 12V, 24V, and 48V systems. It can accommodate up to 10A of current, making it well suited for a variety of applications. It also features over-current protection and thermal protection, to protect the load from damage.

In summary, the DS3680MX/NOPB is a highly capable device that can be used in many different applications. It is designed to operate efficiently and reliably in harsh automotive environments, and its over-current and thermal protection make it perfect for powering high-current loads. In addition, its switched capacitor filter allows it to switch from an on to an off state quickly, making it well suited for applications that require fast dimming or stroboscopic flicker.
