General Description
MC33023 General Description
The MC34023 series are high speed, fixed frequency, singleended pulse width modulator controllers optimized for high frequency operation. They are specifically designed for OffLine and DCtoDC converter applications offering the designer a costeffective 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.
Also included are protective features consisting of input and reference undervoltage lockouts each with hysteresis, cyclebycycle current limiting, and a latch for single pulse metering.
The flexibility of this series allows it to be easily configured for either current mode or voltage mode control.
