    8-Channel Parallelable
    1A Buck DC/DCs
    FEATURES DESCRIPTION 8-Channel Independent Step-Down DC/DCs
    n Master-Slave Configurable for Up to 4A per Output
    Rail with a Single Inductor
    n Independent V Supplies for Each DC/DC
    IN (2.25V to 5.5V)
    n All DC/DCs Have 0.8V to V Output Range
    IN
    n Precision Enable Pin Thresholds for Autonomous
    Sequencing
    n 1MHz to 3MHz Programmable/Synchronizable
    Oscillator Frequency (2MHz Default)
    n Die Temperature Monitor Output
    n Thermally-Enhanced 38-Lead QFN (5mm Г— 7mm)
    and TSSOP Packages The LTCВ®3374 is a high efficiency multioutput power supply IC. The DC/DCs consist of eight synchronous buck
    converters (1A each) all powered from independent 2.25V
    to 5.5V input supplies. n APPLICATIONS General Purpose Multichannel Power Supplies Industrial/Automotive/Communications The DC/DCs may be used independently or in parallel to
    achieve higher currents of up to 4A per output with a shared
    inductor. The common buck switching frequency may be
    programmed with an external resistor, synchronized to an
    external oscillator, or set to a default internal 2MHz clock. ...
