LV5771QA: Step-down Voltage Switching Regulator

LV5771QA is a step-down voltage switching regulator.

特性
  • Wide Input dynamic range: 8V to 42V
  • Built-in Pulse-By-Pulse over-current protection circuit, it detects over-current which used ON-resistance of external MOS-FET.
  • Over current protection: HICCUP MODE
  • Built-in output voltage correction circuit
  • Droops when frequency FOLD BACK is negative
  • Thermal shutdown
  • Load-independent soft start circuit
  • Over voltage protection
优势
