DESCRIPTION  
•
Ideal for Multiple Output and/or High  
Voltage Output Voltage Converters  
The UC3827 family of controller devices provides an  
integrated control solution for cascaded buck and  
push-pull converters. These converters are known as  
current fed or voltage fed push-pull converters and  
are ideally suited for multiple output and/or high  
voltage output applications. In both current fed and  
voltage fed modes, the push-pull switches are driven  
at 50% nominal duty cycles and at one half the  
switching frequency of the buck stage. In the current  
fed mode, the two switches are driven with a speci-  
fied over-lap period to prevent ringing and voltage  
stress on the devices. In the voltage fed mode, the  
two switches are driven with a specified gap time  
between the switches to prevent shorting the trans-  
former across the energy storage capacitor and to  
prohibit excessive currents flowing through the de-  
vices.

Wide Bandwidth, Low Offset,  
Differential Current Sense Amplifier  
The converter's output voltage is regulated by pulse  
width modulation of the buck switch. The UC3827  
contains complete protection and PWM control func-  
tions for the buck converter. Easy control of the  
floating switch is accomplished by the floating drive  
circuitry. The gate drive waveform is level shifted to  
Precise Short Circuit Current Control
