SG1626/SG2626/SG3626
TYPICAL APPLICATIONS
FIGURE 12.
When the SG3626 is driven from a totem-pole source with a peak output greater than 6 volts, a low-current, fast-switching blocking
diode is required at each logic input for protection. In this push-pull converter, the inverted logic outputs of the 3527A are ideal
control sources for the power driver.
FIGURE 13.
In this forward converter circuit, the control capabilities of the SG3524B PWM are combined with the powerful totem-pole drivers
found in the SG3626. This inexpensive configuration results in very fast charge and discharge of the power MOSFET gate
capacitance for efficient swithing.
