The LM5115A controller contains all of the

necessary to produce multiple tracking outputs using 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. LM5115A can be also used as a standalone DC/DC synchronous buck controller (Refer to Synchronous Buck section). Regulation of the auxiliary output voltage is achieved by leading edge pulse width modulation (PWM) of the main channel duty.
