The input operating range of the LT3999 is programmed with the precision undervoltage and overvoltage lockouts. The supply current is reduced to less than 1μA during shutdown. A user-defined RC time constant provides an adjustable soft-start capability by limiting the inrush current at start-up.
The LT3999 is available in a 10-lead Micro Small Outline Package (MSOP) and a 10-pad Dual Flat No Lead (DFN) package with exposed pad. Both package options are RoHS compliant.
