Application Notes
CoolConverter™
Galaxy’s proprietary CoolConverter™ provides:
• Patented 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.
• Low common-mode noise as a result of lower capacitance
in the transformer from balanced winding design.
Protection and Control
Undervoltage Lockout
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.

Input Voltage (V)
ON/OFF Logic Option:
Overvoltage Lockout
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 standard part number. The ON/OFF
pin has a built-in pull up resistor of approximately
100kΩ to +5V.

Application Notes
Output Over Voltage Protection:
Trim:
The output voltage is constantly monitored by the
microprocessor with a redundant secondary-side
measurement circuit that both shuts down the duty cycle
and triggers the microprocessor to shut down. 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. The Trim-down equation applies to all Voltages.

(for 3.3V)
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.
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
Trim-up for less than 1.5V:
Vo (100+∆%) (100+2∆%)

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.

Remote Sense:
Trim-down
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.
Safety:
An external input fuse must always be used to meet
these safety requirements.
