| Description | The IS31LT3954A is a DC-to-DC switching converter that integrates an N-channel MOSFET to operate in a buck configuration. The device can operate from a wide input voltage between 4.5V and 38V and provides a constant current of up to 3A for driving a single LED or multiple series connected LEDs. The external resistor, RISET, is used to set a constant LED output current, while allowing the output vo... |
