TEA1723BT GreenChip SP SMPS demo board
5. Performance data
5.1 No-load input power consumption
Test condition: The no-load input power is measured after a 20 minute warm-up time.
5.2 Output voltage and efficiency
Test condition: The efficiency and VI power characteristics are measured after a
20 minute warm-up time.
Table 3
and Figure 5 show the efficiency figures and VI characteristics measured of the
GreenChip SP TEA1723BT demo board.
