The maximum load efficiency is over 90%, and the no load losses are less than 200mW when powered from a 400VDC input voltage.
27W Sonar Power Supply Reference Design
PMP8709: The PMP8709 reference design shows a SEPIC power supply, which converts input voltages between 8V and 32V to an output voltage of 13.5V. The maximum load current is 2A. Output capacitors are ceramic only.
36V-72VDC Input Active Clamp Forward With Dual 12V/50W Outputs
PMP4028: This power supply design generates a 12V/100W isolated output from a standard 48V telecom input. An active clamp forward converter is controlled by the UCC2897A. The INA202 and an external PFET are used to provide a current limited 12V/4.5A output derived from the main 12V output of the forward converter. This power supply has a peak efficiency of over 94%.
Boost (50V @ 1A)
PMP5940: This 24V to 50V continuous mode boost converter delivers 50W max with efficiency greater than 96%. The circuit uses the low cost TPS40210 controller, which implements current mode control.
