Abstract :
Opto-couplers are always the bottleneck of the performance of the voltage regulator modules (VRMs). By employing secondary-side controllers, opto-couplers can be eliminated, resulting in the expansion of the system bandwidth, the improvement of the transient response performance and reliability. This paper describes high power density, high efficiency secondary-side controlled VRM. Implementation details and experimental results are given.
