3.2 Mode Selection

TPS566235 has a MODE pin to select 3 different operation mode at light load. The device reads the voltage on MODE pin during start-up and latches onto one of the MODE options listed below in Table 3-1.

Table 3-1 MODE Pin Resistor Setting
VMODERECOMMENDED MODE RESISTOR RMOPERATION MODE
0 - 0.3 V0 ΩEco-Mode
0.3 V - 1.2 V100 kΩ - 150 kΩOut-of-Audio (OOA)
> 1.2 VConnected to VCC pin (recommend) or > 400 kΩForced CCM (FCCM)

Changing the position of jumper on J3 can modify MODE pin configuration before power on.
