350W Slow Drain Modulation Power Converter
View the Important Notice for TI Designs covering authorized use, intellectual property matters and disclaimers.
The PMP5726 is 350W High Speed Full Bridge Phase Shift ZVT – Galvanic Isolated Full Bridge Synchronous Rectification DC/DC reference design. It is built for telecom applications to supply a RF Power Amplifier stage. The design is utilizing UCC28950 voltage mode forward and average current limitation backward converter (two quadrant converter). It is capable to modulate output voltage from 20V to 32V within 200us (at maximum 200uF of capacitive load) – so called: slow drain modulation. The converter has full load steps capability as well. It is a very small design for high sophisticated telecom applications. The system can be used also for every other two quadrant applications. Input voltage range: 36VDC-60VDC; Output voltage: 20VDC…32VDC (adjustable); Output current: 11.5A (18Apeak)
