IS32LT3961 Overview
The IS32LT3961 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 5V and 60V and provides a constant current of up to 2A for driving a single LED or multiple series connected LEDs. The external high-side resistor, RIS, is used to set a constant LED output current, while allowing the output voltage to be...
