Product Overview

The LTC3125EDCB#TRMPBF is a high-efficiency synchronous step-up DC-to-DC Converter with an accurate programmable average input current limit. The resistor programmable average input current limit is 5% accurate at 500mA and is suitable for a wide variety of applications. In mobile computing, GSM and GPRS cards demand high current pulses well beyond the capability of the PC card and CompactFlash slots. The LTC3125 in concert with a reservoir capacitor, keeps the slot power safely within its capabilities providing a high performance and simple solution. Synchronous rectification produces high efficiency while the 1.6MHz switching frequency minimizes the solution footprint. The current-mode PWM design is internally compensated. Output disconnect allows the load to discharge in shutdown, while also providing inrush current limiting.
  • Programmable average input current limit
  • Supports high current GSM/GPRS load burst
  • Internal current sense resistor
  • Output disconnect in shutdown
  • Soft-start function
  • Low quiescent current Burst Mode® operation
  • Up to 93% efficiency
  • 5% Input current accuracy
