Alpha and Omega Semiconductor, which develops power management chips for notebook PCs and consumer electronics, raised $91 million by selling 5,060,985 shares at $18, within its expected range of $17 to $19. Alpha and Omega is the second chip company to go public in 2010 and follows the successful IPO of broadband video chipmaker MaxLinear (MXL), which has returned more than 20% since its debut in late March. Deutsche Bank Securities and Piper Jaffray acted as joint bookrunners on Alpha and Omega's IPO. The stock is expected to open for trading on Thursday on the Nasdaq under the symbol AOSL.
