Description
The GS-R12F series is a family of high efficiency
step down switching voltage regulator, designed
to replace linear regulators.
Based on ST L5973 device, these non isolated
regulators are suitable for various applications,
including telecom, industry, computer and
distributed power supply system having a wide
range input voltage.

Additional features and protections
5 Additional features and protections
GS-R12F
5.1 Output overvoltage protection
The overvoltage protection, OVP, is realized by using an internal comparator, whose input is
connected to the feedback. It turns off the power stage when the OVP threshold is reached.
This threshold is typically 30% higher than the feedback voltage.
