DUAL HIGH SPEED DRIVER

TYPICAL APPLICATIONS (continued)

SG1626/SG2626/SG3626

FIGURE 14.

In half or full-bridge power supplies, driving the isolation transformers directly from the PWM can cause excessive IC temperatures,

expecially above 100KHz. This circuit uses the high drive capacity of the SG3626 to solve the problem.

FIGURE 15.

A low-impedance resistive divider network can also be used as the interface between the PWM high-voltage logic output and the

SG3626 power driver. In this 200KHz current mode converter, the SG3847 provides control, while the SG3626 provides high

power drive and minimizes ground spiking in the control IC.
