Application Notes
CoolConverter™
Galaxy’s proprietary CoolConverter™ provides:
• Patent Pending 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.
Overvoltage Lockout
Protection and Control
Valid Input Voltage Range:
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 semiconductor devices in
the converter are not damaged by excessive voltage
stress.

ON/OFF Logic Option:
The ON/OFF control logic can be either Negative
(standard) or Positive to enable the converter. For
Negative logic, the ON/OFF pin is brought below 1.0 V
with respect to the –INPUT pin to enable the converter.
For Positive logic, the ON/OFF pin is brought to greater
than 4.0 V with respect to the –INPUT pin. To request
the Positive logic version, add the suffix (P) to the
standard part number. The positive version has a built-
in pull up resistor of approximately 100 kΩ.

Application Notes
Output Over Voltage Protection:
Trim:
The output voltage is constantly monitored by the
microprocessor and a parallel regulation path with an
independent reference. 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 advanced feature prevents the converter
from damaging the load if there is a converter failure or
application error. If non-latching is required, consult
factory.
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.
Trim-down
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 is
required, consult factory.
Trim-down (%)
Control Options:

As the behavior of the circuit is determined by
firmware in the microcontroller, specific customer
requirements such as
RTRIM-DOWN

5.11kΩ
{∆% }
Trim-up
• 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 10% of Vout,
whichever is greater.
