PWR59XX

The PWR59XX Series offers an extensive selection of input and output voltage combinations to choose from, including a 9V output for Cheapernet local area networking. Both single and dual output voltages are available. These miniature, regulated DC/DC converters come in a 24-pin dual-in-line package for applications where space is a concern. The small size is possible through the use of surface mounted devices and manufacturing technologies. SMT processes and omponents
also make it possible to offer the Series with no power derating over an extended temperature range of 25to +85.

A push-pull input stage ensures fixed frequency, nonsaturating operation of the oscillator section of the PWR59XX Series. MOSPOWER transistors are used as high speed switching elements. These rugged devices provide higher frequency to 500kHz operation, and uncomplicated drive circuitry. Reduced component count means higher reliability. High frequency operation means smaller magnetics. Higher isolation voltages are possible, due to the section wound transformer.
Higher frequency operation also means less noise generation within the system's bandwidth.

Linear regulators, used in the output stage, output voltage variations due to line and load changes, also provide shortcircuit current limiting and thermal overload protection
