IR3500A
A negative temperature coefficient (NTC) thermistor should be used for inductor DCR temperature compensation.
The thermistor should be placed close to the inductor and connected in parallel with the feedback resistor, as
shown in Figure 10. The resistor in series with the thermistor is used to reduce the nonlinearity of the thermistor.
