TYPICAL APPLICATIONS
FIGURE 12.
In this push pull converter circuit, the control capailities of the SG1524B PWM are combined with the powerful totem-pole drivers
found in the SG1644 (see SG1626 for example). This inexpensive configuration results in very fast charge and discharge of the
power MOSFET gate capacitance for efficient switching.
FIGURE 13.
When the peak current capabilites of PWM's such as 1525A or 1526B are not sufficient to drive high capacitive loads fast enough,
SG1644 is one solution to this problem. This combination is especially suited for full bridge applications where high input
capacitance MOSFETs are being used. Diodes D1 and D2 are necessary if the leakage inductance of the drive transformer will
drive the output pins negative.
