Fairchild Intros New FAN5037 DC/DC Controller

Fairchild Semiconductor International (San Jose, CA) introduced the FAN5037, an efficient high-power switch-mode dc/dc controller for low-voltage applications that require currents up to 13A. Applications include low-voltage circuits such as high-density ASICs, DSPs, desktop computer interface circuits, peripheral devices and AGP power.

The FAN5037 handles 5V and 12V inputs and has a built-in high-current driver for an external power MOSFET. The output of the FAN5037 can be adjusted between 1.2V and 3.6V and it features conversion efficiencies of up to 88 percent in typical applications. A soft-start function on the FAN5037 reduces the inrush current and output overshoot at startup, minimizing stress on the surrounding components and increasing reliability.

The FAN5037 is available in an eight-pin SOIC package, supplied in either tube or tape-and-reel packaging.

Available now, the price for the FAN5037M is $0.675 for 1,000-piece units with delivery in six to eight weeks ARO.
