180-W, Dual-Channel, Step-Down Converter Reference Design with 97% Efficiency for Server PSU

1 января 2018

The TIDA-01444 reference design for server PSU, PC PSU, and other step-down converter applications implements a 180-W buck, dual-channel DC-DC converter with a regulatory 12-V DC input voltage designed to provide the terminal load voltage with greater than 97% efficiency and good thermal performance. The switching frequency synchronization between the dual channels is easily realized. The true differential remote sense of the dual outputs compensates the line voltage drop providing more accurate voltage for the terminal load. For improved high power density and a low profile, this integrated circuit reference design uses a planar inductor to replace the traditional discrete inductor. This TI Design has complete protection and temperature sense functions.
