LED drivers are special power sources used to control and power light emitting diode or LED components. LED drivers are also known as LED power supplies. LED drivers provide a regulated current or voltage to LED components to ensure optimal performance, reliability, and longevity. The LM3642TLE/NOPB is a high-efficiency, low-cost LED driver solution for high current LED applications. It is a high-side, synchronous, constant-current LED driver, and has a wide input range from 5V DC to 28V DC.

The LM3642TLE/NOPB is designed to drive high-power LEDs such as those used in LED lighting applications. It has several features that make it ideal for LED lighting applications, such as a low-side external load switch, selectable LED current, adjustable LED current, and programmable current limit. The LM3642TLE/NOPB is designed to be used in a wide variety of applications and is designed to be very efficient, requiring minimal power and maximizing battery life in applications that use battery power.

The LM3642TLE/NOPB has a high-side, synchronous, constant-current LED driver, allowing it to drive high-power LEDs from a wide range of input voltages. It is designed to be very efficient, achieving efficiencies of up to 95%. The LM3642TLE/NOPB features a dual-mode operation, allowing it to either operate as a constant-current LED driver in BURST mode, or as a DC-DC buck regulator in FIXED mode. The device supports up to 10 LEDs connected in series, with a selectable LED current, adjustable LED current and programmable current limit.

The LM3642TLE/NOPB has an adjustable output current of up to 1.2A and a programming resistor that can be used to select the LED current. It also has an LED disconnect feature, allowing for the LED to be quickly disconnected from the system for fast current limit programming and testing. The device also features a fault detection system, which will trigger a fault flag when a fault such as an over-current or over-temperature event is detected. This allows for fast fault diagnosis and troubleshooting.
