Product Overview

The LT3995HMSE#PBF is an adjustable frequency monolithic buck Switching Regulator accepts a wide input voltage range up to 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 current while keeping the output ripple below 15mV in a typical application. The LT3995 can supply up to 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. A high efficiency 85mR switch is included on the die along with a boost Schottky diode and the necessary oscillator, control and logic circuitry.
  • Excellent start-up and dropout performance
  • Accurate programmable undervoltage lockout
  • Power good flag
  • Soft-start capability
  • Thermal shutdown protection
  • Current limit foldback with SS override
  • Synchronizable between 250kHz to 2MHz
  • 700nA Low shutdown current
