The LM3404HVMRX/NOPB is a high-voltage monolithic triple-channel LED driver. It is a switched-mode device capable of driving up to three strings of LEDs with up to 48 V outputs. It is designed for power supply systems with regulated or adjustable output current. The LM3404HVMRX/NOPB can drive up to nine LEDs from a single string with a current up to 700 mA. The LM3404HVMRX/NOPB can be used for applications like automated lighting, decorative lighting, and power supply for information displays.

The LM3404HVMRX/NOPB is a pulse width modulated (PWM) "constant current" LED driver. PWM dimming allows the LM3404HVMRX/NOPB to provide simple but adjustable and accurate control of the LED intensity over a large range. The switching frequency is programmable so as to reduce electromagnetic interference (EMI) effects. The LM3404HVMRX/NOPB can be run in either constant current or constant voltage mode, allowing flexibility in the LED string configuration.

The LM3404HVMRX/NOPB has multiple high-voltage protection features. Under-voltage lockout and over-voltage lockout prevent the driver from operating when the input is outside of its specified operating range, and short circuit protection prevents the driver from operating when a short occurs on the output side.

The LM3404HVMRX/NOPB has a wide input voltage range, from 12V to 72V, making it suitable for use in many different applications. The device also includes frequency hopping and spread spectrum modulation, which allow it to operate in the presence of potential interference sources. Additionally, the device features a low profile, enabling easy integration into end applications.

The LM3404HVMRX/NOPB offers an adjustable output current from 10 mA to 700 mA, as well as adjustable PWM dimming from 0 to 100%. It is designed for applications requiring up to 48 V output, with 200 mA to 700 mA peak current. The LM3404HVMRX/NOPB is an ideal solution for driving LEDs in lighting applications, such as automotive, architectural, and decorative lighting.
