GreenChip SMPS control IC
7.12 Low power operation
In low power operation switching losses are reduced by lowering the switching frequency.
The converter switching frequency is reduced and the peak current is set to 25 % of the
maximum peak current (see Figure 8 and Figure 11).
7.13 Driver (DRIVER pin)
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. This allows for a fast
turn-on and turn-off of the power MOSFET for efficient operation.
7.14 OverTemperature Protection (OTP)
Integrated overtemperature protection ensures the IC stops switching if the junction
temperature exceeds the thermal temperature shutdown limit.
OTP is a latched protection and it can be reset by removing the voltage on pin VCC.
