Si3460-EVB
6.7. R43 and R47
Resistors R43 and R47 together dissipate about 1 W of power during normal operation. Resistors R43, R47, and
R44 (127 ) are chosen based on the IEEE minimum disconnect current specifications and to ensure good
transient response for sudden load changes. To help ensure that heat dissipated by R43 and R47 does not unduly
contribute to the heating of the PCB, it is recommended to move these resistors away from other heat-dissipating
components, such as switching FET M1, inductor L1, and switching diode D8.
