LT1912EDD#PBF

LT1912 is an Adjustable frequency monolithic step-down switching regulator that accepts input voltages upto 36V. A high efficiency 0.25ohm 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. It 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). It is widely used in application such as automotive battery regulation, set-top box, distributed supply regulation, industrial supplies, wall transformer regulation etc.
