Description

PMP9385 is a synchronous dual-phase boost converter accepts an input voltage of 14V to 15.5V, and outputs 24V, capable of providing 8A of current to the load.

Features
  • High efficiency design
  • Synchronizable to external clock
  • Cycle-by-Cycle current limit with programmable hiccup mode overload protection
  • Current-sharing accuracy of < +/-10%
  • Bypass Mode capable when Vin > Vout
  • Low component temperature rise
