Product Summary

The MC33023DWG is a high speed, fixed frequency, single-ended pulse width modulator controller optimized for high frequency operation. The MC33023DWG is specifically designed for Off-Line and DC-to-DC converter applications offering the designer a cost-effective solution with minimal external components. These integrated circuits feature an oscillator, a temperature compensated reference, a wide bandwidth error amplifier, a high speed current sensing comparator, and a high current totem pole output ideally suited for driving a power MOSFET.
