MATERIAL: Units are encapsulated in a low

thermal resistance molding compound which

has excellent chemical resistance, wide oper-

ating temperature range, and good electrical

properties under high humidity environments.

The encapsulant and outer shell of the unit have

UL94V-0 ratings. Lead material is brass with

a solder plated surface to allow ease of solder-

ability.

Product Data Sheet

DESCRIPTION

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, regu-

lated 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 components

also make it possible to offer the Series with no power derating

over an extended temperature range of –25°C to +85°C.

A push-pull input stage ensures fixed frequency, non-

saturating operation of the oscillator section of the PWR59XX

Series. MOSPOWER transistors are used as high speed switch-

ing elements. These rugged devices provide higher frequency

to 500kHz operation, and uncomplicated drive circuitry. Re-

duced component count means higher reliability. High fre-

quency 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 short-

circuit current limiting and thermal overload protection.
