APPLICATION INFORMATION
FIGURE 7 - 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 achieved with speed-up capacitors C1 and C2 .
The low source impedance of the output drivers provides rapid
charging of power FET input capacitance while minimizing exter-
nal components.
Low power transformers can be driven directly by the SG1525A.
Automatic reset occurs during deadtime, when both ends of the
primary winding are switched to ground.
