Product Overview

The LTC3784EUFD#PBF is a high-performance PolyPhase® single output synchronous boost Converter Controller drives two N-channel power MOSFET stages out-of-phase. Multiphase operation reduces input and output capacitor requirements and allows the use of smaller inductors than the single-phase equivalent. Synchronous rectification increases efficiency, reduces power losses and eases thermal requirements, simplifying high power boost applications. A 4.5 to 60V input supply range encompasses a wide range of system architectures and battery chemistries. When biased from the output of the boost converter or another auxiliary supply, the LTC3784 can operate from an input supply as low as 2.3V after start-up. The operating frequency can be set within a 50 to 900kHz range or synchronized to an external clock using the internal PLL. PolyPhase® operation allows the LTC3784 to be configured for 2, 3, 4, 6 and 12-phase operation.
  • PolyPhase® operation reduces required input and output capacitance and power supply induced noise
  • Synchronous operation for highest efficiency and reduced heat dissipation
  • RSENSE or inductor DCR current sensing
  • 100% Duty cycle capability for synchronous MOSFET
  • Power good output voltage monitor
  • Internal LDO powers gate drive from VBIAS or EXTVCC
  • Low shutdown current of IQ <4µA
  • 1.200V (±1%) Reference voltage
  • 28µA Low quiescent current
  • 75 to 850kHz Phase-lockable frequency range
