  • Method for using a programmable operating frequency for a DC-to-DC converter for use with embedded wireless products
    Publication number: 20060072350
    Abstract: A method for determining the switching frequency of a DC-to-DC power supply for a portable radio transceiver (300) includes determining a first group of switching frequencies (301) and then determining the switching harmonics based on that group of switching frequencies (305). These switching harmonics are then compared to a group of desired radio channels (311) where it is then determined if the switching frequencies interfere with the group of desired radio channels (313). Based on these results, a second group of switching frequencies is selected if the first set of switching frequencies provides an undesired level of interference (317, 319, 321).
