Description

The MBRA340T3 is an adjustable frequency monolithic buckswitching regulator that accepts a wide input voltage rangeup to 42V. Low quiescent current design consumes only2.7&mu;A of supply current while regulating with no load. Lowripple Burst Mode operation maintains high efficiency atlow output currents while keeping the output ripple below15mV in a typical application. The LT3975 can supply upto 2.5A of load current and has current limit foldback tolimit power dissipation during short circuit. A low dropoutvoltage of 500mV is maintained when the input voltagedrops below the programmed output voltage, such asduring automotive cold crank.An internally compensated current mode topology is usedfor fast transient response and good loop stability. A highefficiency 75m&Omega; switch is included on the die along with aboost Schottky diode and the necessary oscillator, control,and logic circuitry. An accurate 1.02V threshold enable pincan be driven directly from a microcontroller or used as aprogrammable undervoltage lockout. A capacitor on theSS pin provides a controlled inrush current (soft-start).A power good flag signals when VOUT reaches 91.6% ofthe programmed output voltage. The MBRA340T3 is availablein a small 16-lead MSOP package with exposed pad forlow thermal resistance.
