LMP8350MA/NOPB Application Field and Working Principle

Linear - Amplifiers - Special Purpose refers to a range of devices that are used to amplify electrical signals in a linear range. In particular, the LMP8350MA/NOPB is an adjustable, frame current driver amplifier, which is capable of providing good current regulation and very low noise. This device is typically used in power management applications such as laptop LCD panel backlight displays, automotive lamps, and LED lighting.

Application Field

The LMP8350MA/NOPB device is best suited for boosting current up to 10A. This helps minimize power losses, as the device only needs a limited number of components to provide precise current regulation. Additionally, the chip requires a very low level of noise, making it ideal for applications that require precise current regulation. This makes the LMP8350MA/NOPB device suitable for power management applications such as LED lighting, laptops LCD panel backlight displays, and automotive lamps.

Working Principle

The LMP8350MA/NOPB type of device contains an operational amplifier, which is used for controlling the current delivery. This operational amplifier serves as the power stage for current regulation. An external programmable reference voltage is connected to the chip, which serves as a setpoint for the adjustable frame current. The design allows the current to be regulated with high accuracy, while also providing good ripple rejection and very low noise performance.

The LMP8350MA/NOPB device is also protected against the effects of overcurrent conditions, and it also comes with an open detector which will be activated when the feedback loop of the amplifier is opened. This allows the device to protect itself against possible damages in the event of external fault conditions.

The LMP8350MA/NOPB is a great choice for power management applications, due to its precise current regulation, low noise operation and open detector protection.
