ISSI IS32LT3951 | Demoboard IS32LT3951-GRLA3-EB

Description

IS32LT3951 DEMO BOARD GUIDE The IS32LT3951 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 1.5A for driving a single LED or multiple series connected LEDs. Rev. A, 11/12/2018
