Thermal shutdown
Output voltage programming (GS-R12F0002.0 only)
Loop compensation (GS-R12F0002.0 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
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
The GS-R12F0002.0 output voltage is 5.54 V ± 4 %, to reduce this value connect a resistor
between pin 11 (FB) and pin 10 (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 11 (FB) and pin 10 (V
will act as speed up (see
