7.15 Limitation of the maximum switching frequency
At high mains, the maximum switching frequency is limited (see Figure 14). The 130 kHz
switching frequency is required at low mains only. At high mains, the high switching
frequency during peak power causes an unnecessary high voltage on the drain of the
MOSFET, because the high switching frequency increases the clamp voltage.
7.16 Driver (pin DRIVER)
The driver circuit to the gate of the power MOSFET has a current sourcing capability of
typically 300 mA and a current sink capability of typically 750 mA. These capabilities
enable a fast turn-on and turn-off of the power MOSFET for efficient operation.
7.17 OverTemperature Protection (OTP)
If the junction temperature exceeds the thermal shutdown limit, integrated
overtemperature protection ensures that the IC stops switching.
OTP is a latched protection. It can be reset by removing the voltage on pin VCC.
