Business Description
The company designs, develops and markets proprietary, high-voltage analog integrated circuits for use in AC to DC power conversion. The company has targeted high volume power supply markets, including cellular telephone, personal computer and other mkts The Company is initially focusing on those markets that are sensitive to size, portability, energy efficiency and time-to-market. The Company believes its patented TOPSwitch ICs, introduced in 1994, are the first highly integrated power conversion ICs to achieve widespread market acceptance. The Company introduced an enhanced family of ICs, TOPSwitch-II, in April 1997. Virtually every electronic device that plugs into a wall socket requires some type of power supply to convert high-voltage, alternating current ("AC") into low-voltage, direct current ("DC"). A large segment of the power supply market in the 0.5 to 150 watt power range consists of switching power supplies ("switchers") which typically use a high-voltage discrete semiconductor along with other components to perform the power conversion. Discrete solutions, which emerged in the 1970's, have not kept pace with the rapid integration trends in the electronics industry and require numerous components and a high level of system complexity compared to a more highly integrated IC solution.

Competition
The high-voltage power supply industry is intensely competitive and characterized by extreme price sensitivity. Accordingly, the most significant competitive factor in the target markets for the Company's products is cost effectiveness. The Company's products face competition from alternative technologies,primarily discrete switchers. The Company believes that at current pricing, the TOPSwitch families of products offer favorable cost performance benefits compared to discrete switchers in many high-volume applications over the power range of approximately 0.5 watts to 150 watts. However, any significant erosion in the price of discrete components, such as high-voltage Bipolar and MOSFET transistors and PWM controller ICs, could adversely affect the cost effectiveness of the TOPSwitch products. Also older alternative technologies to switchers are more cost-effective than switchers that use the Company's TOPSwitch products in certain power ranges for certain applications. If power requirements for certain applications in which the Company's products are currently utilized, such as battery chargers for cellular telephones, drop below certain power levels, these older alternative technologies can be used more cost effectively than TOPSwitch-based switchers. The Company is continuing its efforts to use its extensive system level expertise to enhance the cost effectiveness of TOPSwitch-based switchers in the lower power ranges. There can be no assurance that the Company will be successful in these efforts. Recently, the Company's TOPSwitch product families have begun to meet additional competition from hybrid and single high-voltage ICs similar to TOPSwitch. These competing products are being developed or have been developed and are being produced by companies such as Motorola, SGS, Samsung and Sanken. The Company expects competition to increase as Motorola, SGS, Samsung, Sanken and possibly other companies develop and introduce new products. To the extent these competitors' products are lower in cost than the Company's products, the Company's business, financial condition and results of operations could be materially and adversely affected. Many of the Company's emerging competitors, including Motorola, SGS, Samsung and Sanken, have significantly greater financial, technical, manufacturing and marketing resources than the Company. In the context of a market where a high-voltage IC is designed into a customer's product and the provider of such ICs is therefore the sole source of the IC for that product, greater resources and, in particular, greater manufacturing resources, may be a significant factor in the customer's choice of the IC because of the customer's perception of greater certainty in its source of supply. The Company's ability to compete in its target markets also depends on such factors as the timing and success of new product introductions by the Company and its competitors, the pace at which the Company's customers incorporate the Company's products into their end user products, availability of wafer fabrication and finished good manufacturing capability, the availability of adequate sources of raw materials, protection of Company products by effective utilization of intellectual property laws and general economic conditions. There can be no assurance that the Company's products will continue to compete favorably or that the Company will be successful in the face of increasing competition from new products and enhancements introduced by existing competitors or new companies entering this market. Failure of the Company to compete successfully in the high-voltage power supply business would materially and adversely affect the Company's business, financial condition and results of operations.

Business Plan
The company's objective is to be the leading provider of high-woltage power conversion ICs. The company intends to pursue the following strategies to accelerate adoption of its products: (I) Target High-Volume Markets, (ii) Focus on Markets that Can Derive Significant Benefits from Integration, (iii) Deliver Systems Solution and Provide Applications Expertise, (iv) Extend Technological Leadership in High-voltage Analog ICs, and (v) Leverage Patented Technology in Strategic Partnerships.

Use of Proceeds
The proceeds from the proposed offering will be used for working capital and general corporate purposes as well as the repayment of subordinated debt..
