Application Notes
CoolConverter™ Family
Galaxy’s COOLCONVERTERS™ feature:
• Single-stage power conversion architecture, control, and
magnetic design allow unprecedented power density and
efficiency in an isolated power supply.
• An advanced microcontroller reduces parts count while
adding features, performance, and flexibility in the design.

The converter measures the input voltage and will
not allow operation outside of the input voltage
specification. As shown by the graphs, hysteresis is
added to both the high and low voltage to prevent
the converter from turning on and off repeatedly
when the voltage is held near either voltage extreme.
At low line this assures the maximum input current is
not exceeded; at high line this assures the semicon-
ductor devices in the converter are not damaged by
excessive voltage stress.

Input Voltage (V)
ON/OFF Logic Option:
The ON/OFF control logic can be either Negative
(standard) or Positive to enable the converter. For
Negative logic, bring the ON/OFF pin to less than
1.0V with respect to the –INPUT pin to enable the
converter. The pull-down must be able to sink
100µA. For Positive logic, bring the ON/OFF pin to
greater than 4.0V with respect to the –INPUT pin
and be limited to less than 10V. To request the
Positive logic version, add the suffix (P) to the stan-
dard part number. The ON/OFF pin has a built-in pull
up resistor of approximately 100kΩ to +5V.

APPLICATION NOTES
Output Over Voltage Protection:
Safety:
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 on the ON/OFF pin or power to
the converter. This advanced feature prevents the
converter from damaging the load if there is a con-
verter failure or application error. If non-latching is
required, consult factory.
An external input fuse must always be used to meet
these 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, con-
nect the required trim resistor from the Trim pin to
the –Sense pin. See diagram below.
Thermal Shutdown:
The baseplate temperature is monitored with a PTC
thermal sensor. If the maximum rated temperature is
exceeded, the converter behaves as described in the
specifications (latch or auto-restart). If the converter
is the latching type, it is re-enabled by either cycling
the power or enable ON/OFF. If the converter is the
non-latching type, it will restart when the temperature
decreases below the trip point and no less than 2
seconds, whichever occurs later.

• custom valid input voltage range

• controlled delay from initiating an ON/OFF signal

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 1V.
