DESCRIPTION

The LT®3492 is a triple output DC/DC converter designed to operate as a constant-current source and is ideal for driving LEDs. A frequency adjust pin allows the user to program switching frequency between 330kHz and 2.1MHz to optimize efﬁciency and external component size. Each of the three channels has a built-in gate driver to drive an external LED-disconnect P-channel MOSFET, allowing high dimming range. The output current range of each channel of the LT3492 is programmed with an external sense resistor. The CTRL pin is used to adjust the LED current either for analog dimming or overtemperature protection.
