Fairchild Unveils FAN5093 Synchronous Buck Controller

Fairchild Semiconductor International (San Jose, CA) announced the FAN5093 two-phase, single-chip, synchronous buck controller with integrated high-current super drivers, which demonstrate gains in conversion efficiency of over 10 percent when compared to competing three-phase solutions, according to the company.

Operating from a single 12V supply, the FAN5093 features programmable active droop, which achieves 100nsec transient response while requiring minimal output capacitance. A five-bit VID DAC allows precision dynamic adjustment of the output voltage between 1.10V and 1.85V. Other features include power-good indication, output enable/soft start, under-voltage lockout, over-voltage protection, and adjustable current limiting.

The FAN5093 is available in a 24-pin TSSOP package. Pricing is $3.75 each in 1,000-piece quantities. Samples are available now with production quantities delivered in seven to eight weeks ARO.
