Description
General part information
LTC3374A Series
The LTC3374A is a multioutput power supply IC consisting of eight synchronous 1A buck converters, all powered from independent 2.25V to 5.5V input supplies. An upgraded pin-compatible version of the LTC3374, the LTC3374A, has higher efficiency, improved output voltage accuracy and an added overvoltage (OV) indicator.The DC/DCs may be used independently or in parallel to achieve higher output currents of up to 4A 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 simplify powerup sequencing. The LTC3374A is available in a 38-lead 5mm × 7mm QFN package as well as a 38-lead exposed pad TSSOP package.NOTESLTC3374LTC3374AHigher efficiency, improved output voltage accuracy and an added overvoltage (OV) indicatorAPPLICATIONSGeneral Purpose Multichannel Power SuppliesIndustrial/Automotive/Communications
