1.2.5 S-CONF Resistor

R1 selects the switching frequency when no jumper is installed in J1. R1 selects the settings for spread spectrum, output discharge, and clock synchronization settings. This resistor can be changed or a jumper can be used with J1 to select the VIN (2.2 MHz) or GND (1 MHz) settings. See the TPS62913 data sheet for details.
