APPLICATION NOTES

Output Over Voltage Protection:

The output voltage is constantly monitored by the

microprocessor. If the output voltage exceeds the

over-voltage specification, the microprocessor will

latch the converter off. To turn the converter on

requires either cycling the ON/OFF pin or power to

the converter. This feature prevents the converter

from damaging the load if there is a converter

failure or application error. If non-latching is

required, consult factory.

Thermal Shutdown:

The printed circuit board temperature is measured

using a semiconductor sensor. If the maximum

rated temperature is exceeded, the converter is

latched off. To re-enable the converter requires

cycling the ON/OFF pin or power to the converter.

If non-latching shutdown is required, consult

factory.

Control Options:

As the behavior of the circuit is determined by

firmware in the microcontroller, specific customer

requirements such as:

• non-latching thermal protection

• custom valid input voltage range

• controlled delay from initiating an ON/OFF

signal for power sequencing can be

accomplished with no change to hardware.

The standard behavior was chosen based on

system design experience but we understand that

customers often have their own requirements.

Please consult Galaxy Power for your special

needs.

Remote Sense:

The output voltage is regulated at the point where

the sense pins connect to the power output pins.

Total sense compensation should not exceed 0.4V

or 2% of Vout, whichever is greater.

Safety:

An external input fuse must always be used to

meet safety requirements.

Trim:

To trim the output voltage higher, connect the

required trim resistor from the Trim pin to the

+Sense pin. To trim the output voltage lower,

connect the required trim resistor from the Trim pin

to the –Sense pin. See diagram below.
