OUTPUT SECTION
APPLICATION INFORMATION
For single-ended supplies, the driver outputs are grounded. The
V
transistors on alternate oscillator cycles.
The low source impedance of the output drivers provides rapid
charging of power FET input capacitance while minimizing exter-
nal components.
C
terminal is switched to ground by the totem-pole source

In conventional push-pull bipolar designs, forward base drive is
controlled by R
are achieved with speed-up capacitors C
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.
