600mA, 1.2MHz Micropower

LTC3400

$600.00價格
  • The LTC®3400/LTC3400B are synchronous, fixed frequency,
    step-up DC/DC converters delivering high efficiency
    in a 6-lead ThinSOT™ package. Capable of supplying
    3.3V at 100mA from a single AA cell input, the devices
    contain an internal NMOS switch and PMOS synchronous
    rectifier.
    A switching frequency of 1.2MHz minimizes solution
    footprint by allowing the use of tiny, low profile inductors
    and ceramic capacitors. The current mode PWM design is
    internally compensated, reducing external parts count.
    The LTC3400 features automatic shifting to power saving
    Burst Mode operation at light loads, while the LTC3400B
    features continuous switching at light loads. Antiringing
    control circuitry reduces EMI concerns by damping the
    inductor in discontinuous mode, and the devices feature
    low shutdown current of under 1mA.
    Both devices are available in the low profile (1mm)

    SOT-23 package.
