10 Power Supply Recommendations

Because the driver draws current from the VCC pin to bias all internal circuits, for the best high-speed circuit performance, two VCC bypass capacitors are recommended to prevent noise problems. The use of surface-mount (SM) components is highly recommended. A 1μF ceramic capacitor should be placed as close as possible to the VCC to ground pad of the gate driver.
