Fairchild Semiconductor's FAN9612 controller provides over 96% power conversion efficiency for AC-DC power supplies, according to the company.
Applications include power supplies for digital TVs, desktop and entry-level server computers, front-end telecom systems and industrial power systems rated from 100W to 1000W.
By interleaving and keeping two power stages precisely at 180 degrees out of phase timing under all operating conditions, the FAN9612 lowers conduction losses, the input filter size and board space by as much as 10%compared to alternate solutions, the company said.
