DC DC Switching Controllers

synchronous boostpeak current modeAEC-Q100HTSSOP-20multiphase capableexternal MOSFET controller

LM25122QPWPRQ1 is an automotive-qualified synchronous boost controller for wide-input, high-current boost designs requiring external N-channel MOSFETs.

Best for

  • Wide-input synchronous boost converters
  • Automotive power conversion
  • High-current multiphase boost stages

Avoid if

  • A complete integrated power converter is required
  • The input or switch-node voltage exceeds the stated ratings

Check before use

  • External MOSFET voltage, current, and gate-charge ratings
  • Inductor saturation current
  • Current-limit setting
  • Compensation stability
  • PCB thermal and switching-loop layout
