APPLICATION INFORMATION POWER DISSIPATION The SG1644, while more energy-efficient than earlier gold-doped driver IC’s, can still dissipate considerable power because of its high peak current capability at high frequencies. Total power dissipation in any specific application will be the sum ...

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 ...
