MC34023, MC33023
High Speed Single-Ended PWM Controller
The MC34023 series are high speed, fixed frequency, single−ended pulse width modulator controllers optimized for high frequency operation. They are 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.
Also included are protective features consisting of input and reference undervoltage lockouts each with hysteresis, cycle−by−cycle current limiting, and a latch for single pulse metering.
