Features

Overtemperature Protection, Thermal Sensor, Latching* 120 °C Switching Frequency, Fixed 330 kHz Notes: During short circuit, converter will shut down and attempt to restart once per second. The average current during this condition will be very low and the device can be safely left in this condition continuously. For specific output voltage specifications, see the corresponding detailed data sheet. *PCB less than 130 °C. OVP set to limit maximum voltage in system to a safe level. This can be adjusted for higher voltages if needed.

Bolero HV Series, Page 3 Part No. 02–004 Rev. 1.9.5–102502PRODUCT PREVIEw CoolConverter™ Family Galaxy’s COOLCONVERTERS™ feature:

• 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. Application Notes 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. For Positive logic, the ON/OFF pin is brought to greater than 4.0V with respect to the Enable. To request the Positive logic version, add the suffix (P) to the standard part number. The Input pin has a built-in pull-up resistor of approximately 100kΩ to +5.0V .

Bolero HV Series, Page 4 Part No. 02–004 Rev. 1.9.5–102502PRODUCT PREVIEw APPLICATION NOTES Output Over Voltage Protection: The output voltage is constantly monitored by the microprocessor. 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 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 shutdown 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 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 2% of V out, whichever is greater. Safety: An external input fuse must always be used to meet safety requirements. Trim: 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. External Output Trimming + Sense Trim – Sense Trim-down (%) Trim-up (%) Trim-down Trim-up (for 3.3V) RTRIM-DOWN = 100 – 2 kΩ∆%{ }
