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.

P SUFFIX  
CASE 648  
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.

The flexibility of this series allows it to be easily configured for  
either current mode or voltage mode control.
