MOSFETs - Single

PWM power switchoffline converternon-isolatedbuckbuck-boostSOP-7150 V MOSFET

U3213D is an SOP-7 offline non-isolated PWM power switch for low-power buck or buck-boost converters, integrating a 150 V MOSFET and high-voltage startup circuit.

Best for

  • Low-power non-isolated offline buck converters
  • Small-appliance auxiliary supplies
  • Industrial-control power stages

Avoid if

  • The required Drain transient voltage can exceed the 150 V rating
  • Isolation is required
  • Compliance, lifecycle, or MSL documentation is mandatory but unavailable

Check before use

  • Verify input and switching-node surge voltage
  • Measure inductor peak current and overload response
  • Confirm output regulation with the selected FB network
