In summary, NXP’s DC to DC Boost Converters can benefit NFC applications by providing a consistent 5.0 V or 5.25 V output independent of the battery charge level. The NXP DC to DC boost converter family have a proven performance advantage when used with NXP NFC devices, and used with all the major card types; Topaz, Mifare Ultralight, Felica, and Desfire. Advantages of the NXP DC to DC boost converter family are high switching frequency and smaller external components, also lower baseband noise. This delivers greater operating range of the NFC signal, or adoption of smaller antenna size for the same range as larger antennas. These DC to DC Boost Converters may be used in other applications requiring a regulated and boosted voltage at up to 500 mA load current.
