Description

General part information

LTC3370 Series

The LTC3370 is a highly flexible multioutput power supply IC. The device includes four synchronous buck converters, configured to share eight 1A power stages, each of which is powered from independent 2.25V to 5.5V inputs.The DC/DCs are assigned to one of eight power configurations via pin programmable C1-C3 pins. 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 PLL/MODE pin for Burst Mode or forced continuous mode operation. A PGOODALL output indicates when all enabled DC/DCs are within a specified percentage of their final output value.To reduce input noise, the buck converters are phased in 90° steps. Precision enable pin thresholds facilitate reliable power-up sequencing. The LTC3370 is available in a 32-lead 5mm × 5mm QFN package.ApplicationsGeneral Purpose Multichannel Power Supplies: Automotive, Industrial, Distributed Power Systems
