Thermal shutdown
Output voltage programming (GS-R12FP0001.9 only)
Loop compensation (GS-R12FP0001.9 only)
The shutdown block generates a signal that turns OFF the power stage if the temperature of
the internal chip goes higher than a fixed internal threshold (150 °C min).
The sensing element of the chip is very close to the PDMOS area, so ensuring an accurate
and fast temperature detection.
An hysteresis of approximately 20 °C avoids that the devices turns ON and OFF
continuously.
The GS-R12FP0001.9 output voltage is 5.54 V ±4 %, to reduce this value connect a resistor
between pin 10 (FB) and pin 9 (V
The resistor must be located very close to the proper pins, to minimize the injected noise
(see
The resistor value is calculated using the following formula:
Rv = [(V
V
If required by particular load conditions, it is possible to change the feedback loop
compensation, adding an external capacitor between pin 10 (FB) and pin 9 (V
act as speed up (see
