Abstract
A universal adapter for use with a rechargeable handheld communication device includes a power module. An AC rectifier is operable to convert an AC power signal into a rectified AC power signal. A DC transformer is operable to receive the AC rectified power signal and output a DC transformed power signal. A top switch feedback circuit is coupled to the DC transformer and is operable to regulate the DC transformed power signal. A DC to DC switching converter is coupled to the DC transformer and is operable to convert the DC transformed power signal to a converted DC power signal. A feedback control circuit is coupled to the DC to DC converter and operable to regulate the converted DC signal.
