... Typical Application Circuit – IRAM336-025SB Application Circuit Recommendation 1. Electrolytic 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 order to provide good decoupling between VCC-VSS and Vb-Vs terminals, the capacitors shown connected between these terminals should be located very close to the module pins. frequency capacitors, typically 0.1µ ...
