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 under
voltage lockouts each w...
