IS32LT3953 Description
The IS32LT3953 is a DC-to-DC switching converter with an integrated N-channel MOSFET operating in a buck configuration. The device is connected to a voltage higher than the LED voltage; between 6V and 48V and provides a constant current of up to 3.0A for driving a single LED or multiple series connected LEDs.
