LM3405, 1A Constant Current Buck Regulator
Integrated with a 1A power switch, the LM3405 is a current mode control switching buck regulator designed to provide a simple, high efficiency solution for driving LEDs.
With a 0.2V reference voltage feedback control to minimize power dissipation, an external resistor sets the current as needed for
