Description
The LTC®3374 is a high efficiency multioutput power supplyIC. The DC/DCs consist of eight synchronous buckconverters (1A each) all powered from independent 2.25Vto 5.5V input supplies.The DC/DCs may be used independently or in parallel toachieve higher currents of up to 4A per output with a sharedinductor. The common buck switching frequency may beprogrammed with an external resistor, synchronized to anexternal oscillator, or set to a default internal 2MHz clock.The operating mode for all DC/DCs may be programmedvia the MODE pin.To reduce input noise the buck converters are phased in90° steps. Precision enable pin thresholds provide reliablepower-up sequencing. The LTC3374 is available in acompact 38-lead 5mm × 7mm QFN package as well as a38-lead TSSOP package.
