Application Notes
CoolConverter™ Family
™
Galaxy’s COOLCONVERTER Family features:
• 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 compared to planar magnetics and metal
baseplate designs.
• Higher reliability than planar transformer designs that can
suffer from via fatigue from thermal cycling, and metal
baseplate designs with board to board interconnects that are
subject to mechanical stress on electrical connections.
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
1.0V with respect to the -INPUT pin to enable the
converter. The pull-down must be able to sink
100µA. For Positive logic, the ON/OFF pin is
brought 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 and a redundant secondary side
crowbar circuit that is set to a higher trip point than
the microprocessor protection. If the output voltage
exceeds the over-voltage specification, the
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.
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.
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 shutdown is required, consult
factory.

– 2 kΩ
{∆% }
Control Options:
As the behavior of the circuit is determined by
firmware in the microcontroller, specific customer
requirements such as:
Trim-up (for 3.3V)
• 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.

Designed for higher di/dt and ∆I applications, the
transient response has been modified to take
advantage of the capacitance on the customer's
PCB. This unit requires a minimum load
capacitance of 5600µF with an impedance
magnitude of less than 0.005Ω at 15kHz. It offers a
