Fairchild Semiconductor Adds New Advanced Load Switches for Portable Applications

Fairchild Semiconductor announced its FPF214X and FPF216X series of IntelliMAX™ advanced load switches, which the company claims feature superior thermal performance and full system protection for portable applications operating between 1.8 and 5.5V.

Available in a 2mm x 2mm green-compliant MicroFET™ MLP package, the FPF214X and FPF216X series are said to offer 45% enhanced thermal performance compared to traditional SOT-23 packages. These highly integrated advanced load switches are claimed to simplify design, reduce component count and minimize board space by integrating a 0.11Ω current-limited P-channel MOSFET with protection and control features, including thermal shutdown, controlled turn-on, reverse-current blocking and under-voltage lockout (UVLO).

"Fairchild’s IntelliMAX integrated load switch solutions with higher current limits up to 1500mA and 2mm x 2mm MLP packaging offer critical protection features and thermal efficiency for small form factor power management designs," said Chris Winkler, Marketing Director, Low-Voltage Power Segment. "The latest portable applications, such as smart phones and integrated MP3/video media players, are packed with features that require additional battery-charging and auxiliary power supplied through a USB connector or other accessory interface. By integrating important functionality into an ultra-compact MLP package, these advanced load switches are ideal for today’s new slimmer and lighter portable electronics."

These products utilize lead-free (Pb-free) terminals and have been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. All Fairchild products are designed to meet the requirements of the European Union Directive on the restriction of the use of certain hazardous substances (RoHS).

The products are priced (each, 1000 pcs) between $0.72 and $0.78. Samples and demos are available now, with a delivery time of 10-12 Weeks ARO.
