LT3995HMSE#PBF

LT3995 is an adjustable frequency monolithic buck switching regulator that accepts a wide input voltage range upto 60V. Low quiescent current design consumes only 2.7µA of supply current while regulating with no load. Low ripple Burst Mode operation maintains high efficiency at low output currents while keeping the output ripple below 15mV in a typical application. This device can supply upto 3A of load current and has current limit foldback to limit power dissipation during short circuit. A low dropout voltage of 500mV is maintained when the input voltage drops below the programmed output voltage, such as during automotive cold crank. An internally compensated current mode topology is used for fast transient response and good loop stability. It is widely used in application such as automotive battery regulation, portable products, industrial supplies etc.
