PRINCIPLES OF OPERATION AND TYPICAL CHARACTERISTICS
Output Saturation Characteristics
For single ended supplies, the driver outputs are
grounded. The VC terminal is switched to ground by the
totem-pole source transistors on alternate oscillator cycles.
In conventional push-pull bipolar designs, forward base
drive is controlled by R1-R3. Rapid turn-off times for the
power devices are acheived with speed-up capacitors C,
and C2.
Output Circuit ( Circuit Shown)
The low source impedance of the output drivers provides
rapid charging of power FET input capacitance while
minimizing external components.
Low power transformers can be driven directly by the
UC1525B. Automatic reset occurs during dead time, when
both ends of the primary winding are switched to ground.
