OPERATION OF VOLTAGE REGULATOR FOR SUBSYSTEM IN CONSTANT CURRENT MODE AND THEN IN CONSTANT VOLTAGE MODE

摘要

At power, a voltage regulator operates in a constant current mode to provide a constant current to a subsystem. The constant current is predetermined as an optimal current to provide to the subsystem to reach normal operation in a temporally efficient manner. When a voltage provided by the voltage regulator reaches a threshold voltage, the voltage regulator operates in a constant voltage mode to provide a constant voltage to the subsystem.
