APPLICATION INFORMATION
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.
The low source impedance of the output drivers provides rapid
charging of power FET input capacitance while minimizing exter-
nal components.
For single-ended supplies, the driver outputs are grounded. The
V
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 R
- R
. Rapid turn-off times for the power devices
are achieved with speed-up capacitors C
1
and C
2
.
