The module has an efficiency of 80% to 95%. It has a number of built-in protections, including input current limiting, undervoltage lockout and thermal shutdown.

Connections

  • PG - Open drain output which goes low when the regulator output voltage increases more than 7.5% above or drops more than 9% below the nominal voltage
  • VIN - input voltage
  • GND - ground
  • VOUT - output voltage
  • EN - turning on the converter
