Product Overview

The LTC3370IUH#PBF is a 4-channel 8A configurable buck DC/DC Converter includes four synchronous buck converters, configured to share eight 1A power stages. The DC/DC converters 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.
  • 8 Unique output configurations
  • Low total no load supply current
  • Precision enable pin thresholds for autonomous sequencing
  • Temp monitor indicates die temperature
  • PGOODALL pin indicates all enabled bucks are in regulation
