LTC3374EUHF#PBF

LTC3374 is a high efficiency multioutput power supply IC. The DC/DCs may be used independently or in parallel to achieve higher currents of upto 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. The operating mode for all DC/DCs may be programmed via the MODE pin. To reduce input noise the buck converters are phased in 90° steps. Precision enable pin thresholds provide reliable power-up sequencing. It is used in application such as general purpose multichannel power supplies, industrial/automotive/communications etc.
