Over-Temperature Protection (OTP) The over-temperature circuit limits the junction tempera- ture of the APW7506C. When the junction temperature exceeds 150oC, a thermal sensor turns off the both power MOSFETs, allowing the devices to cool. The thermal sen- sor allows the converters to start a soft-start process and regulate the output voltage again after the junction tem- perature cools by 30oC. The OTP is designed with a 30oC hysteresis to lower the average Junction Temperature (T J) during continuous thermal overload conditions, in- creasing the lifetime of the device. Short-Circuit Protection When the output is shortened to the ground, the frequency of the oscillator is reduced to about 210kHz, 1/7 of the nominal frequency. This frequency foldback ensures that the inductor current has more time to decay, thereby pre- venting runaway. The oscillator ’s frequency will progres- sively increase to 1.5MHz when V FB or VOUT rises above 0V. |
