Frequently Asked Questions
What is the maximum output current the LM3407MY/NOPB can deliver to an LED string?
The LM3407MY/NOPB supports a maximum LED output current of 350 mA, enabling it to drive a single high-brightness LED or a short LED string with consistent regulated current, ensuring stable luminous flux across varying input voltages.
Which input voltage range does the LM3407MY/NOPB support for typical LED driver circuits?
The device accepts input voltages from approximately 3 V up to 40 V, making it compatible with a wide range of DC power rails including 5 V, 12 V, and 24 V systems commonly used in industrial and consumer LED lighting designs.
How does PWM dimming work with the LM3407MY/NOPB and what frequency range is recommended?
PWM dimming is achieved by applying a digital signal to the enable pin, toggling the device on and off at frequencies typically between 100 Hz and 1 kHz. This method maintains constant color temperature while adjusting perceived brightness by varying the duty cycle from 0% to 100%.
Is LM3407MY/NOPB a suitable alternative to a resistor-limited LED driver in a 24 V industrial panel?
Yes. Unlike resistor-limited designs that dissipate excess voltage as heat and vary current with supply fluctuations, LM3407MY/NOPB provides a regulated 350 mA constant-current output over a 3 V to 40 V input range, improving efficiency and LED lifespan in 24 V industrial panel applications.
