Synaptics files for IPO

Synaptics, which makes touch pads used in notebook computers, filed Thursday with the Securities and Exchange Commission for an initial public offering. The San Jose, Calif.-based company plans to raise up to $50 million, but did not specify the number of shares it will sell or the price range.

Synaptics counts several high-profile companies among its customer base, including Apple Computer, Compaq Computer, Dell Computer, Gateway and Hewlett-Packard. The company said in its filing it hopes to capitalize on the growing market for personal digital assistants, smart phones and other mobile devices. The company has applied to trade on the Nasdaq Stock Market under the ticker symbol "SYNA." Bear Stearns, Banc of America Securities, SG Cowen and ING Barings will handle the sale.
