  • Power input voltage range variable 3.8V to 18V
  • PWM output voltage adjustable from 0.6V
  • Up to 12A output load
  • Prebias start-up, fixed 3ms soft-start
  • Selectable fSW of 300kHz, 600kHz, and externalsynchronization up to 1MHz
  • Peak current mode control
  • DCM/CCM
  • Thermally compensated current limit
  • Internal/external compensation
  • Open-drain, PG window comparator
  • Output overvoltage and thermal protection
  • Input overvoltage protection
  • Integrated boot diode with undervoltage detection
  • Selectable OCP schemes
  • Hiccup OCP
  • Latch-off
  • Compact size 3.5mmx3.5mm

Typical applications

  • Telecom and networking systems, Servers and cloud infrastructure POLs
  • Storage systems
  • Test measurement, IPCs, factory automation, PLCs
