High Speed SingleEnded
PWM Controller
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.
