Cell phones our personal link to our world whether we are talking, testing or simply taking a pictures we need to stay connected there is nothing can stop us staring our tracks like a dead cell phone battery. Hi I am Paul Fikel the RF power products applications engineer of Fairchild semiconductor a dead cell phone battery it’s a nightmare for anyone who depends on cell phones for work or play the solutions to keeping cell phones powered up no nothing this massive. Fairchild semiconductor provides small powerful solutions to process its problem uncounted by every cell phone user the FAN59O2 a Fairchild Semiconductor extends talk time by reducing the dc power consumptions in 3G mobile handsets it’s a small and cost effective IC that brings to you in free minutes lets look at the rural problem and see how the FAN59O2 solves it inside phone every is a radio frequency transmitter every time you talk ,text send data the transmitter drains power out of the battery after consumes only 10 percent of the phones total power but if you have poor coverage , surf the net or upload files such as photos the transmitters battery consumptions can top 6 times that sapping 60 percent of the battery’s charge the bottom-line a transmitter can bear huge power drain dramatically reduce the talk time.
No matter what type of phone you used here is the solution Fairchild semiconductor is developed a best in class DC to DC converter that solves its problem, even though it’s tiny the FAN59O2 saves a substantial amount of power how does it work phones waste power by connecting the transmitter directly to the battery the transmitter has much more voltage than it need and waste power the FAN59O2 eliminates that waste by dynamic pre-scaling the voltage supply. The voltage increases when the power amplifier has to deliver more RF power and decreases when less power is needed.
The FAN59O2 eliminates the power wasted when the amplifier is connected to recruit the battery. And you phone designers like this using the FAN59O2 reduces key dissipation and the heat sync size making lighter and smaller phone possible. it works with any DC to DC enable power amplifier any lower costs amplifier and it doesn’t degrade the signal quality or pollute the RF spectrum, see the signal is not degraded by the FAN59O2 the adjacent channels are clean and there are no spirals stones in receive bands this means the phones use on were not only have more talk time but it can also be smaller and lighter with improve performance and what this means to a handset user is that its small cost effective solution will extent talk time by 20, 30 or even up to 40 minutes. The FAN59O2 for Fairchild semiconductor is the optimum solution in reducing the DC power consumption to extend the talk time in 3Gmobile handsets go to www.fairchildsemi.com/rfpower where you will find the FAN59O2 datasheet and more
I am Paul Fikel from Fairchild semiconductor thank you.
