the pulse current necessary for efficient switching, the output of the isolated DC-DC converter (pins 17, 18 and 19)
must be decoupled using a combination of low impedance electrolytic and film capacitors. In Figure 5 the 150µF
low impedance electrolytics and a 2.2µF stacked film or multi-layer ceramic are included for this purpose. These
capacitors should be located as close as possible to the pins of the hybrid gate driver. When driving small
modules it is usually acceptable to use smaller capacitors provided that that they have sufficient ripple current
capability and low enough impedance. However, very large modules and parallel module applications may require
500µF or more to achieve low enough impedance and high enough ripple current capability.

feedback signal. The optocoupler is connected from the common of the isolated power supply (pin 18) to the fault
signal pin using a 470Ω current limiting resistor. When a fault occurs a current of approximately 10mA will flow in
the optocoupler’s LED. A 3.3kΩ resistor connected across the opto’s photodiode helps to improve noise immunity.
