and TSSOP Packages The LTC®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. …
