6MHz 1A Constant Current Buck Regulator for Powering LEDs ADVANCE INFORMATION October 2006 LM3405 550kHz/1.
6MHz 1A Constant Current Buck Regulator for Powering LEDs General Description 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 driving various types of LEDs.
Switching frequency is internally set to 550kHz (LM3405-Y) or 1.
6MHz (LM3405-X), allowing small surface mount inductors and capacitors to be used...
