Dual Phase Synchronous Buck
PMP7884: This is a dual-phase, synchronous buck converter with an input voltage range of 30.6V-to-37.4Vin and an output of 9Vout @ 15A.
12V/400W Dual-Phase 1/4 Brick Buck Converter Reference Design Delivers 97% Peak Efficiency
PMP7819: This 400W ¼ brick DC/DC converter leverages the LM5119’s dual-phase capability to drive a 33A load in an industry-standard ¼ brick module footprint. This compact design delivers 97% peak efficiency while maintaining balanced current through each phase, which reduces thermal stress and enables lower system cost by eliminating the need to over-design the surrounding power components.
Reference Design for Telecom Applications (24V @ 0.5A)
PMP4742.2: PMP4742.2 is a simple and efficient non synchronous boost converter. It boosts the input 12V to 24V at 150mA nominal, 500mA maximum. Its enable pin is driven by power good signal from the hot swap TPS2420.
Reference Design for Telecom Applications (12V @ 1.1A)
PMP4742.1: PMP4742.1 comprises a negative input (-10.8V to -13.2V) to positive output (12V@1A average) inverting buck-boost converter with TPS40210; a hot swap circuit with TPS2420 quickly limits the output current to 2A peak.
Reference Design for Telecom Applications (3.3V @ 5A)
PMP4742.3: PMP4742.3 protects the 12Vin by means of hot swap controller (TPS2420) and feeds a TPS54620, syncronous buck converter, which generates 3.3V@3.7A. An INA210 reads the buck's current for monitoring purposes.
