Linear Technology LTC3374A

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.

APPLICATIONS

nn General Purpose Multichannel Power Supplies nn Industrial/Automotive/Communications The LTC®3374A 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 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.
