Sales Strategy Identifying the Application Power supplies: isolated (AC:DC or DC:DC) with regulated 3.3V (or lower) output. Power for sub-2.5V integrated circuits (e.g., microprocessors). Step-down power conversion (step down) when minimal periphery components, cost, and size are the focus.

Sales Strategy Product Positioning Sell the LX8580A In Applications 1)Requiring low-voltage and high current. 2)Requiring 2.9V (and lower); where 5.0V and 3.3V is available. 3)Where small volume packaging is required.

Sales Strategy Facts to Remember LX8580A –Is specified from 0 to 125°C. –Comes in industry standard packages. –Has the same pin-out as most competitors.
