Summary
Modules with input voltages up to 80 V are specially de-
signed for secondary switched and battery driven applica-
tions. The case design allows operation at nominal load up
to 71°C without additional cooling.
The PSC series of positive switching regulators is designed
as power supply modules for electronic systems. Their ma-
jor advantages include a high level of efficiency that re-
mains virtually constant over the entire input voltage range,
high reliability, low ripple and excellent dynamic response.
