of the input supply as well as the load current. Typically, with a 3 V input supply the weak-regulator output is 2.525 V and its output

impedance is approximately 40 Ω.

4.2.2.2.3 LDO_USB

The LDO_USB module implements a programmable linear-regulator function from the USB VBUSB voltages (4.4 V–5.5 V) to

produce a nominal 3.0 V output voltage. A programmable brown-out detector is included in the regulator that can be used by the

system to determine when the load capability of the regulator is being exceeded, to take the necessary steps. This regulator has

a built in power-mux that allows the user to select to run the regulator from either USB VBUS supply, when both are present. If

only one of the USB VBUS voltages is present, then, the regulator automatically selects this supply. Current limit is also included

to help the system meet in-rush current targets.

For additional information, see the

i.MX RT1060X Reference Manual (IMXRT1060XRM).

4.2.2.2.4 DCDC

DCDC can be configured to operate on power-save mode when the load current is less than 50 mA. During the power-save

mode, the converter operates with reduced switching frequency in PFM mode and with a minimum quiescent current to maintain

high efficiency.

DCDC can detect the peak current in the P-channel switch. When the peak current exceeds the threshold, DCDC will give an alert

signal, and the threshold can be configured. By this way, DCDC can roughly detect the current loading.

DCDC also includes the following protection functions:

• Over current protection. In run mode, DCDC shuts down when detecting abnormal large current in the P-type power switch.
