Beschreibung
- PMP7282, 35V-60V Input,12V/600W 2-Phase Buck Converter. PMP7282 is a 2-phase buck converter capable of 600W output power. This design uses two LM5116 emulated current-mode synchronous buck controllers in a master/slave configuration. An LMC555 timer provides synchronization with 180 degrees between the two phases to minimize input and output ripple current. Current sharing is accomplished using an LMC7101 Op-Amp, which forces the control voltage of the slave to follow that of the master. An LMV431 is used to control a pass regulator for the 5V Op-Amp and timer supply. The LMV431 also provides the reference voltage for the Op-Amp, which matches the internal reference of the LM5116 for proper tracking
