SLVSFC5 November 2020 TPS552882
PRODUCTION DATA
By placing different resistors between the MODE pin and the AGND pin, the TPS552882 selects the internal power supply or external power supply for VCC, and also selects PFM mode or forced PWM mode in light load conditions. Table 7-2 shows the resistance values for each selection.
RESISTOR VALUE (kΩ) | VCC SOURCE | OPERATING MODE AT LIGHT LOAD |
---|---|---|
0 | Internal | PWM |
24.9 | Internal | PFM |
51.1 | External | PWM |
Open | External | PFM |
