The LT®3496 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 regulators is independently operated by that channel’s PWM signal. The PWM feature allows precise adjustment of the color mixing or dimming ratio of the LED source. 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 LT3496 is programmed with an external sense resistor. The CTRL pin is used to adjust the LED current either for analog dimming or overtemperature protection. L, LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
