3.2 Mode Selection

TPS56C230 has a MODE pin to select the operation mode. 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 Settings
VOLTAGE ON MODER9/10/11/12 (kΩ)R13/14/15/16 (kΩ)OPERATIONFREQUENCY (kHz)
(0~10%)*VCC33015Eco-mode500
(10~20%)*VCC18033FCCM500

Change the position of the jumper on J4 to modify the MODE configuration before start up.
