Description

General part information

LT1912 Series

The LT1912 is an adjustable frequency (200kHz to 500kHz) monolithic step-down switching regulator that accepts input voltages up to 36V. A high efficiency 0.25Ω switch is included on the die along with a boost Schottky diode and the necessary oscillator, control and logic circuitry. Current mode topology is used for fast transient response and good loop stability. The LT1912 allows the use of ceramic capacitors resulting in low output ripple while keeping total solution size to a minimum. The low current shutdown mode reduces input supply current to less than 1μA while a resistor and capacitor on the RUN/SS pin provide a controlled output voltage ramp (soft-start). The LT1912 is available in 10-pin MSOP and 3mm × 3mm DFN packages with exposed pads for low thermal resistance.ApplicationsAutomotive Battery RegulationSet-Top BoxDistributed Supply RegulationIndustrial SuppliesWall Transformer Regulation
