Application Scenarios & Design Considerations

High Performance Resonant Mode Controller

Alternative Part Number

  • UC3846DW --: Industry-standard current-mode PWM controller in the same SOIC-16 package, widely used as a functional substitute for the MC33067 in switching power supply designs.
  • SG3525ADW --: Voltage-mode PWM controller in SOIC-16 with similar drive and oscillator features, commonly cross-referenced for Motorola MC33067 applications.
  • TL494CD --: General-purpose PWM control IC with dual outputs and wide availability, suitable as a lower-cost alternative when exact pin compatibility is not critical.
