LM3414HVMR/NOPB

PMIC - LED Drivers

The LM3414HVMR/NOPB is an example of a PMIC, which stands for Power Management Integrated Circuit. This device is specifically designed to drive LED of all types, such as Light Emitting Diode (LED) or Organic Light Emitting Diode (OLED). It has many applications, including automotive, indoor and outdoor LED lighting displays, and other LED based products.

The LM3414HVMR/NOPB is a current regulated, Buck-Boost LED driver that can be used to drive a single LED up to a certain wattage. It can be used in various topologies such as buck, boost, buck-boost, and flyback. It also has the unique ability to control either the input voltage, or the output current, which makes it quite versatile.

The main feature that makes this driver unique is its integrated feedback circuit. This allows the regulator to adjust the voltage or current at the output depending on the feedback it receives from the LED. Additionally, the driver will correctly adjust the output voltage or current depending on the forward drop of the diode, which helps the user to achieve the best possible efficiency.

In addition to this feedback circuit, the LM3414HVMR/NOPB also has other useful features. It has a low quiescent current mode, enabling the driver to be power efficient. It also has adjustable frequency operation, allowing the user to select the appropriate frequency for their application, and also includes an Over-temperature Protection (OTP) mechanism for enhanced safety.

Overall, the LM3414HVMR/NOPB is an excellent PMIC for driving LED of all types, especially for automotive and other LED-based products. Its integrated feedback circuit and adjustable frequency operation give the user a great amount of flexibility in controlling LED operations, while its low quiescent current mode helps to ensure a high efficiency of the circuit.
