LT3684IMSE#PBF

LINEAR TECHNOLOGY  LT3684IMSE#PBF  直流-直流开关降压逐步递减稳压器, 可调, 3.6V-36V输入, 1.265V-20V输出, 2A输出, MSOP-10

The is an adjustable frequency monolithic buck Switching Regulator accepts input voltage up to 34V 36V maximum. A high efficiency 0.18R 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 LT3684"s high operating frequency allows the use of small, inductors and 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. A power good flag signals when VOUT reaches 90% of the programmed output voltage.
