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. In power save mode, DCDC stop charging inductor when detecting large

current in the P-type power switch. The threshold is also different in run mode and in power save

mode: the former is 1 A–2A, and the latter is 200 mA–250 mA.

• Over voltage protection. DCDC shuts down when detecting the output voltage is too high.

• Low voltage detection. DCDC shuts down when detecting the input voltage is too low.

For additional information, see the i.MX RT1015 Reference Manual (IMXRT1015RM).
