In May 2007, Fairchild Semiconductor introduced the new high-frequency integrated boost converter FAN5336, which allows designers to achieve 87% system efficiency, low EMI and save board space. It is widely used for small LCD bias and white LED backlighting. design. This 1.5MHz switching frequency boost converter features a wide output voltage range (9V-33V) and integrates the switching NFET in an ultra-thin molded leadless package (UMLP) measuring only 3mm x 3mm x 0.6mm in. The FAN5336 is smaller than the usual SOT package, but offers more features, including higher peak current (1.5A), 1.0A higher than competing devices; excellent input and load regulation (0.2%) High switching frequency (1.5MHz). As a result, the FAN5336 helps minimize noise and heat generation in cell phones and smartphones, MP3 players, medical devices, and many other portable applications. In addition, the converter's high frequency allows the use of smaller components to help designers make the best use of board space while reducing design complexity.

In July 2007, Fairchild Semiconductor introduced the new IntelliMAX family of devices, the FPF250X, with an input voltage of 4.5V-20V. These highly integrated load switches provide comprehensive protection against potential overcurrent damage that can impact low-power designs in industrial, telecom, medical, notebook, and consumer applications. The FPF250X device integrates a 0.23 ohm current-limited N-channel MOSFET with protection and control functions such as thermal shutdown, controlled conduction, and undervoltage lockout in a space-saving SOT23 package, simplifying design, reducing component count and Reduce the board area.
