XC9111C331MR is a fixed 3.3 V PFM boost converter with an integrated switch and CE shutdown control for low-voltage battery-powered designs.

Best for

  • Low-voltage boost rails
  • Battery-powered portable electronics
  • 3.3 V regulated outputs

Avoid if

  • A tightly specified low-ripple supply is required without validating PFM ripple
  • The required output current exceeds the verified application-curve conditions

Check before use

  • Input start-up and hold voltage
  • Load current at minimum input voltage
  • External component voltage and current ratings
  • CE control connection
