CoolConverter™
Bel Power’s Proprietary CoolConverter™
• 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.
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 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 (P) to the
standard part number. The ON/OFF pin has a built-in pull-up resistor of approximately 100kΩ to +5V.
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.

Protection and Control (continued)
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.
Control Options
As the behavior of the circuit is determined by firmware in the microcontroller, specific requirements, such as:
• 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 customers may have their own requirements. Please contact Bel Power for any 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 2% of Vout, whichever is greater.
Safety
An external input fuse must always be used to meet these safety requirements.
External Output Trimming
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.
