LM34966QPWPRQ1 is an automotive-qualified peak-current-mode controller for non-synchronous boost, SEPIC, and flyback power stages. It supports a wide BIAS range, programmable switching frequency, and external N-channel MOSFET drive.

Best for

  • Automotive boost, SEPIC, and flyback converters
  • Wide-input battery-powered power stages
  • Applications requiring external MOSFET selection and current sensing

Avoid if

  • A fully integrated power converter with internal MOSFET is required
  • The design cannot accommodate external compensation and magnetics design

Check before use

  • Confirm BIAS operating range and 45 V absolute maximum transient exposure
  • Confirm MOSFET gate charge satisfies QG@VCC × fSW < 20 mA
  • Check current-limit and slope-compensation behavior at maximum duty cycle
  • Use the recommended low-inductance switching and current-sense layout
