Frequently Asked Questions

What is the maximum input voltage for LM3402MM/NOPB?

The LM3402MM/NOPB supports a maximum input voltage of 42V, making it suitable for automotive and industrial applications with wide supply voltage ranges, including 12V and 24V bus systems.

What LED current can LM3402MM/NOPB drive?

The LM3402MM/NOPB provides a constant output current of up to 0.5A (500mA) for LED driving. The output current is set using an external sense resistor, allowing precise control of LED brightness and ensuring consistent light output across temperature variations.

What dimming methods does LM3402MM/NOPB support?

LM3402MM/NOPB supports both PWM dimming and analog dimming. PWM dimming is achieved by toggling the EN/DIM pin, which turns the converter on and off at a user-defined frequency. Analog dimming adjusts the LED current by varying the voltage on the control pin, enabling smooth continuous brightness control.

What package is LM3402MM/NOPB available in?

LM3402MM/NOPB is available in a VSSOP-8 (MM) surface-mount package, which offers a compact footprint suitable for space-constrained LED driver designs in consumer, industrial, and automotive applications.
