LTC3124EFE#PBF информация о продукте

The LTC3124EFE#PBF is a dual-phase, synchronous step-up DC/DC converter with true output disconnect and inrush current limiting capable of providing output voltages up to 15V. Dual-phase operation significantly reduces peak inductor and capacitor ripple currents, minimizing inductor and capacitor size. The 2.5A per phase current limit, along with the ability to program output voltages up to 15V make the LTC3124EFE#PBF well suited for a variety of demanding applications. Once started, operation will continue with inputs down to 500mV.

The LTC3124EFE#PBF switching frequency can be programmed from 100kHz to 3MHz to optimize applications for highest efficiency or smallest solution footprint. The oscillator can be synchronized to an external clock for noise sensitive applications. Selectable Burst Mode operation reduces quiescent current to 25μA, ensuring high efficiency across the entire load range. An internal soft-start limits inrush current during start-up.

Other features include a <1μA shutdown current and robust protection under short-circuit, thermal overload, and output overvoltage conditions. The LTC3124EFE#PBF is offered in both 16-lead DFN and thermally-enhanced TSSOP packages.


  • VIN Range: 1.8V to 5.5V, 500mV After Start-Up
  • Adjustable Output Voltage: 2.5V to 15V
  • 1.5A Output Current for VIN = 5V and VOUT = 12V
  • Dual-Phase Control Reduces Output Voltage Ripple
  • Output Disconnects from Input When Shut Down
  • Synchronous Rectification: Up to 95% Efficiency
  • Inrush Current Limit
  • Up to 3MHz Programmable Switching Frequency Synchronizable to External Clock
  • Selectable Burst Mode® Operation: 25μA IQ
  • Output Overvoltage Protection
  • Internal Soft-Start
  • <1μA IQ in Shutdown
  • 16-Lead, Thermally-Enhanced 3mm × 5mm × 0.75mm DFN and TSSOP Packages


  • RF, Microwave Power Amplifiers
