PWR59XX
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 鈥?5掳C to +85掳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鈥檚 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.

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.
