Power Integrations buys Qspeed

Jan 28, 2014

Tweet SAN JOSE, Calif. - Power Integrations Inc. has recently acquired Qspeed Semiconductor, a supplier of high-performance high-voltage diodes, for a price of approximately $7 million in cash. Qspeed diodes utilize a proprietary silicon technology to provide a unique combination of high efficiency and low noise, as well as high-frequency operation, which reduces the cost and size of magnetic components in a power supply. Power Integrations, a supplier of high-voltage integrated circuits for energy-efficient power conversion, also announced financial results for the quarter and fiscal year ended Dec. 31, 2010. Net revenues for the fourth quarter were $73.0 million, up 10 percent compared with the fourth quarter of 2009, and down three percent compared with the third quarter of 2010. Net income was $8.9 million or $0.30 per diluted share, compared with $9.2 million or $0.32 per diluted share in the year-ago quarter and $12.6 million or $0.43 per diluted share in the third quarter of 2010. Full-year revenues for 2010 were $299.8 million, an increase of 39 percent compared with 2009. Net income for the full year was $1.67 per diluted share, more than double the $0.82 per diluted share reported in the prior year. Non-GAAP net income for the full year was $2.00 per diluted share, an increase of 69 percent from $1.18 per diluted share in the prior year. Commented Balu Balakrishnan, president and CEO of Power Integrations: "2010 was a landmark year for Power Integrations, as shipments surpassed one billion units and we approached $300 million in annual revenues. We grew our top line by 39 percent, achieving our ninth consecutive year of revenue growth. We also had an excellent year from a profitability standpoint, expanding our non-GAAP operating margin by more than five percentage points and growing our non-GAAP earnings by more than 75 percent. " The company issued the following forecast for the first quarter of 2011: Revenues are expected to be between $71 million and $77 million. In October, Power Integrations announced a strategic investment in SemiSouth Laboratories, a Mississippi-based manufacturer of high-voltage silicon-carbide (SiC) power devices. Last month a federal district court awarded Power Integrations double damages in one of its patent-infringement lawsuits against Fairchild Semiconductor, increasing the award to approximately $12.9 million. The ruling followed an earlier finding that Fairchild's infringement of Power Integrations' patents was willful. Power Integrations recently announced seven new members of its LinkSwitch-PH family of LED driver ICs. The new devices (LNK413-LNK419) are suitable for lighting applications ranging from 3 W bulbs to 55 W replacements for fluorescent lighting fixtures. The devices, which can achieve up to 88 percent efficiency, feature a PWM-dimmable single-stage controller with both power factor correction (PFC) and accurate constant current (CC) power conversion functionality. The integrated PFC and CC functions allow multiple drivers to be connected in parallel to drive exterior and street area lights efficiently and with functional redundancy. LinkSwitch-PH devices incorporate the PFC/CC controller, a 725 V MOSFET and MOSFET driver into a single package, which simplifies layout and design and eliminates parasitic elements between the controller and MOSFET. The new ICs enable the ultimate in high reliability at low cost by eliminating up to 25 additional components used in traditional isolated flyback designs, including the high-voltage electrolytic bulk capacitor and the optocoupler — the components most likely to limit the lifetime of an LED lamp.
