.. LM25115 Secondary Side Post Regulator Controller November 2005 LM25115 Secondary Side Post Regulator Controller General Description The LM25115 controller contains all of the Features necessary to implement multiple output power converters utilizing the Secondary Side Post Regulation (SSPR) technique. The SSPR technique develops a highly efficient and well regulated auxiliary output from the secondary side switching waveform of an isolated power converter. Regulation of the auxiliary output voltage is achieved by leading edge pulse width modulation (PWM) of the main channel duty cycle. Leading edge modulation is patible with either current mode or voltage mode...
