Abstract

Methods and circuits for linearly controlling a limited, constant current during startup of LDOs, amplifiers, or DC-to-DC converters independent of load capacitor size and controlling a clean transition without glitches from a constant current (CC) mode during startup to a constant voltage (CV) mode during normal operation (CC-CV method) are disclosed. The constant current control loop and the constant voltage control loop are implemented in such a way that at the end of startup the voltage loop has taken over control and the current loop is moved far away from its active transistor region, allowing a switch of modes to occur without any nasty transitions on the output.
