... NTC thermistor must be connected from this pin to ground. The impedance of the NTC thermistor decreases whenever the temperature increases. Once the voltage of the OTP pin drops below 1.2V, the SG6980D will be off, and will auto restart when the voltage is back to 1.4V. The resistance of a resistor connected between RI and ground determines the switching frequency. A resistor with a resistance between 15kΩ ...
