Description

PMP7969 is a very high efficiency 4 phase boost controller synchronizable to external clock. Light load efficiency is excellent due to phase shedding capability. Synchronous rectifier also improves efficiency. High effective switching frequency obtained with multiphase over single phase, and current sharing accuracy of ±10%. Bypass mode capable when Vin > Vout.

Features
  • Very high efficiency at lower loads due to phase shedding capability
  • Synchronizable to external clock
  • Stackable for higher output currents
  • Current sharing accuracy of ±10%
  • Bypass mode capable when Vin > Vout
  • High effective switching frequency obtained with multiphase over single phase
