LM3407EVAL: 350mA @ 24.5V Max, 22 ~ 30V in


The LM3407 evaluation board contains a Pulse-Width-Modulation (PWM) floating buck converter with an integrated N-Channel power MOSFET and is designed to provide a constant current output for driving 350mA LEDs.

The switching frequency is selectable between 300 kHz and 1MHz by changing the value of the frequency setting resistor.
