Summary:

TI's high-density primary-side DC/DC brick power solution combines an integrated synchronous FET controller capable of operating at switching frequencies up to 2 MHz with ultra-low Qg NexFETs for unprecedented power density A smaller and more efficient DC/DC power supply.

Key features of TI solutions:

• 100Vdc input voltage
• Allows power to operate from many common input voltage rails used in the telecom and industrial market segments
• Low voltage and high current output
• High efficiency at low voltage and high current through a combination of synchronous FET architecture and NexFET high performance FETs
• High power density solution
• Integrated driver and high efficiency enable a smaller overall footprint because the reduction in heat generation makes the board layout more compact
