Application Notes
™
CoolConverter
Bel Power’s Proprietary CoolConverter™
•
•
An advanced microcontroller reduces parts count while
adding features, performance and flexibility in the design.
Patented single-stage power conversion architecture,
control and magnetic design allow unprecedented
power density and efficiency in an isolated power
supply.
•
Low common-mode noise results from lower capacitance
in the transformer from balanced winding design.
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.
Over Voltage Hysteresis
1.0
ON/OFF Logic Option
The ON/OFF control logic can be either Negative (standardꢀ
or Positive to enable the converter. For Negative logic, the
ON/OFF pin is brought to 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 (Pꢀ to the standard part number. The
ON/OFF pin has a built-in pull-up resistor of approximately
100kΩ to +5V.

Input Voltage (V)
Under Voltage Hysteresis

Output Over Voltage Protection
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 required
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.

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.

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.
Safety
An external input fuse must always be used to meet these
safety requirements.
