General Description
Features
The FAC2576 is a series of easy to use fixed and
adjustable step-down (buck) switch-mode voltage
regulators. These devices are available in fixed
output voltage of 3.3V, 5V, and an adjustable
output version. Both versions are capable of
driving a 3A load with excellent line and load
regulation.
Requiring a minimum number of external
components, these regulators are simple to use
and include internal frequency compensation, and
a fixed-frequency oscillator.
The output voltage is guaranteed to ±3%
tolerance under specified input voltage and
output load conditions. The oscillator frequency is
guaranteed to ±15%. External shutdown is
included, featuring typically 80 µA standby current.
Self protection features include a two stage
frequency reducing current limit for the output
switch and an over temperature shutdown for
complete protection under fault conditions.
The FAC2576 is available in TO-220B-5L
TO220-5L and TO-263-5L packages.
