5.2.2 Compensation network

Both LDO and DC/DC voltage regulators use VCORE voltage feedback to control the

output voltage (see 

Figure 12

).

For FS45xx devices using static (steady-state) LDO regulators, a simple resistor bridge

(resistors R3 and R6) determines the feedback voltage. By default, the feedback voltage

is 1.3 V.
For FS65xx devices using DC/DC voltage regulators, a pair of RC voltage dividers

controls the dynamic behavior of the regulator.

5.2.3 FCRBM Resistor Bridge

The feedback core bridge monitoring (FCRBM) Resistor Bridge is an evaluation board

safety feature.
The bridge generates the same voltage as the bridge connected to the FB_core pin. If

the difference between the two voltages is greater than the VCORE_FB_DRIFT value,

the FS state machine is impacted (refer to data sheet). The drift value is set to 1.3V by

default.
