PSA123-2
Description
Positive Switching Regulators
Manufacturer
POWER-ONE [Power-One]
Datasheet
Summary
The PSA series of positive switching regulators is de-
signed as power supply modules for electronic systems.
Their major advantages include a high level of efficiency
that remains virtually constant over the entire input range,
high reliability, low ripple and excellent dynamic response.

Positive Switching Regulator
[V]
Modules with input voltages up to 60 V are specially de-
signed for secondary switched and battery driven applica-
tions. The case design allows operation at nominal load up
to 50°C without additional cooling.
