3.2.4 TPS650861 and TPSM5D1806 Transient Test Setup

Figure 3-4 TPS650861 and TPSM5D1806 Transient Test Setup

To test the capability of the TPS650861 and TPSM5D1806 devices, the following equipment is needed:

  • Electronic load to provide the current load and provide the transient step
    • Another option is to use a load slammer circuit and use the electronic load to provide the baseline current and use the load slammer circuit to switch between the two currents
  • Oscilloscope to measure the current of the transient and then another to measure the voltage across the capacitor to measure the transient capability of the converter
