Figure 1: Typical Application Connection
1. Bus capacitors should be mounted as close to the module bus terminals as possible to reduce ringing
and EMI problems. Additional high frequency ceramic capacitor mounted close to the module pins will
further improve performance.
2. In order to provide a good decoupling between VCC-VSS abd VB-VS terminals, the capaciotrs shown
connected at these terminals should be located very close to the module pins. Additional high frequency
capacitors, typically 0.1uF, are recommended.
3. Value of the boot-strap capacitors depends upon the switching frequency. Their selection should be
made based on IR Design tip DT04-4 or application note AN-1044.
