PRINCIPLES OF OPERATION AND TYPICAL CHARACTERISTICS
UC1525B Output Circuit (1/2 Circuit Shown)
UC1525B Output Saturation Characteristics
For
single-ended
supplies,
the
driver
outputs
are
grounded. The VC terminal is switched to ground by the to-
tem-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 achieved with speed-up capacitors C,
and C2.
