摘要： A multi-phase converter may include: a plurality of voltage converter circuits connected in parallel; current sensors provided in the voltage converter circuits respectively; and a controller configured to calculate an estimated value of a total input current inputted to the multi-phase converter. The controller may be configured to output an abnormality notification signal indicating abnormality in one of the current sensors when a difference between a total sum of measured values of all the current sensors and the estimated value is outside a predetermined allowable range.

摘要： Provided herein are apparatus and methods for low voltage high power supply rejection ratio (PSRR) systems. A charge pump converts a supply voltage to a larger charge pump voltage and provides the charge pump voltage to a circuit subsystem. The charge pump voltage is regulated to a state dependent reference. In the steady state the charge pump voltage is regulated with respect to an output voltage of the circuit subsystem; in this way PSRR of the circuit subsystem is enhanced.

摘要： Some embodiments relate to charge pump regulators to selectively activate a charge pump based not only on the voltage output of the charge pump, but also on a series of wake-up pulses that are delivered at predetermined time intervals and which are delivered independently of the voltage output of the charge pump. Hence, these wake-up pulses prevent extended periods of time in which the charge pump is inactive, thereby helping to prevent latch-up in some situations.
