6.1 Line/Load Regulation and Efficiency Measurement Procedure

  1. Set up the EVM as described in Section 4.3 and Figure 4-1.
  2. Ensure that the electronic load is set to draw 0 ADC.
  3. Increase VIN from 0 V to 12 V using the DMM to measure input voltage.
  4. Use the other DMM to measure output voltage VOUT.
  5. Vary the load from 0 ADC to maximum rated output ADC (TPS544B20 = 20 A, TPS544C20 = 30 A). VOUT must remain in regulation as defined in Table 2-1.
  6. Vary VIN from 8 V to 14 V. VOUT must remain in regulation as defined in Table 2-1.
  7. Decrease the load to 0 A.
  8. Decrease VIN to 0 V.
