7.4 Device Functional Modes

7.4.1 Normal Operation

When the input voltage is above the UVLO threshold and the EN voltage is above the enable threshold, the

TPS54427 operates in normal switching mode. Normal continuous conduction mode(CCM) occurs when the

minimum switch current is above 0 A. In CM the TPS54427 operates at a quasi-fixed frequency of 650 kHz.

7.4.2 Forced CCM Operation

When the TPS54427 is in normal CCM operating mode and switch current falls below 0 A, the device begins

operating in forced CCM.
