PMIC - LED Drivers are widely used in applications such as consumer electronics and automotive lighting. The LM3406HVMH/NOPB is a high-efficiency current-mode LED driver that can provide a constant-current regulation with a wide input voltage range. It is designed to drive LED strings with up to 3 A of load current.

LM3406HVMH/NOPB features an adjustable fixed frequency peak current-mode architecture, providing a regulated current to the LED strings with a peak current-mode control loop. This architecture provides superior transient response, cycle-by-cycle current limit, and output precision. It also offers a wide duty cycle adjustment range for different applications.

In addition, the LM3406HVMH/NOPB features a low-cost, low-side current sensing for output current regulation. It integrates a wide-range of features such as thermal shutdown protection and overvoltage protection. It is also designed to operate from a wide range of input voltages, and its output current accuracy is maintained over its specified operating range of input voltage.

The LM3406HVMH/NOPB also includes external temperature compensation that enables the LED driver to maintain its accuracy over temperature. The device also includes an input overvoltage protection circuit with a high-voltage supply clamp. This circuit is used to protect the device and its associated components from the potential damage due to excessive input voltage.

LM3406HVMH/NOPB includes a wide range of available options, such as dimming control, soft-start/restart control, PCIe-compatible power input detection and Active-High/Low output current regulation. It also features a start-up illumination time-out option that prevents a system from attempting to start with all LEDs on. This prevents the device from shorting out and helps protect the downstream circuitry.

In addition, it has built-in pin protection features to protect the device from accidental damage. The LM3406HVMH/NOPB also features an internal shift register for programming and setting options such as dimming, soft-start/restart, and time-out settings.
