A Fast Response Current-Compensation Circuit for POL

摘要

A current-compensation circuit system for POLs is introduced. The proposed circuit employs MOSFETs, resistors and capacitors without any discrete magnetic devices. The system is activated only during transient responses and its total power loss is very small. Simulation results revealed that the output POL voltage is maintained within 5% of 1.5 V during a load change between 1 A and 10 A.
