RFS Series: 20W / 6.0A DC/DC Converters Oct 2001 36-75V Input 18-Oct-01 Rev 1.0 Page 9 of 14 www.power-one.com Typical Application This series of converters does not req uire any external components for proper op eration. However, if the distribution of the input voltage to the converter contains significant inductance, a capacitor across the input terminals may be required to stabilize the input voltage. A minimum of 1µF, quality electrolytic / ceramic capacitor is recommended for this purpose. For output decoupling it is recommend connecting a 1µF ceramic capacitor directly across th e output pins of the converter. Shutdown Feature The remote control pin functions as a normal soft shutdown. It is reference d to the – Vin pin. With positive logic, when the remote control pin is pulled low, the output is turned off and the unit goes into a very low input power mode. An open collector switch is recommended to control the voltage between the remote control pin and the -Vin pin of the converter. The remote control pin is pulled up internally, so no external voltage source is required. The user should avoid connecting a resistor between the remote control pin and the +Vin pin. The user must take care to ensure that the pin reference for the control is connected close to the - Vin pin. The control signal must not be referenced ahead of EMI filtering, or remotely from the unit. If the remote control pin is not used, it can be left floating. Thermal Considerations The converter is designed for natural or forced convection cooling. The output power of the converter is limited by the maximum case temperature (Tc). To ensure reliable long term operation of the converters, and to comply with safety agency require ments, Power -One limits maximum allowable case temperature (Tc) to 100°C (see Mechanical Drawings). Output Current Limiting When the output is overloaded above the maximum output current rating, the voltage will start to reduce to maintain the output po wer to a safe level. In a condition of high overload or short -circuit where the output voltage is pulled below approximately 30% of Vo.Nom, the unit will enter a ‘Hiccup’ mode of operation. Under this condition the unit will attempt to restart, approxima tely every 25ms until the overload has cleared. Parallel Operation Paralleling of two converters is not possible. Output Voltage Trim The trim feature allows the user to adjust the output voltage from the nominal. Output voltage can be adjusted by a n external resistor. To increase Vo a resistor should be connected between pins 2 and 3. To decrease Vo a resistor should be connected between pins 1 and 3. To increase Vo: Rext = (A – (D x Vout)) / ( Vout – Vout.Nom) To reduce Vo: Rext = ((B x Vout) - C) / ( Vout.Nom - Vout) Where Vout is the desired output voltage Model A B C D RFS06ZA 1945 1470 1944 470 RFS06ZB 2590 1730 2560 750 RFS06ZD 5010 2516 5010 1500 RFS06ZE 7010 3161 7010 1500 RFS04ZG 11260 4532 11240 1500 Note: When the output voltage is trimmed up, the output power from the converter must not exceed its maximum rating. This is determined by measuring the voltage on the output pins, and multiplying it by the output current.
RFS Series: 20W / 6.0A DC/DC Converters Oct 2001 36-75V Input 18-Oct-01 Rev 1.0 Page 10 of 14 www.power-one.com Safety Considerations These converters feature 1500 Volt DC isolation from input to output. The input to output resistance is greater than 10MOhm. These converters are provided with Operational Insulation between input and output circuits according to EN60950 / UL1950 / CSA60950 -00. Nevertheless, if the system using the converter needs to receive safety agency approval, certain rules must be followed in the design of the system. In particular, all of the creepage and clearance requirements of the end - use safety requirements must be observed. These documents include UL60950, CSA60950 -00 and EN60950, although specific applications may have additional requirements. In order for the output of the converter to be considered as SELV (Safety Extra Low Voltage) or TNV-1, according to EN60950 / UL1950 / CSA60950-00, one of the following requirements must be met in the system design:
- The converter has no internal fuse. An external fuse must be provided to protect the system from catastrophic failure. A fuse with a rating not greater than 2.0A is recommended. The user can select a lower rating fuse based upon the inrush transient and the maximum input current of the converter, which occurs at the minimum input voltage. Both input traces and the chassis ground trace (if applicable) m ust be capable of conducting a current of 1.5 times the value of the fuse without opening. The fuse must not be placed in the grounded input line, if any.
- If the voltage source feeding the module is SELV, the output of the converter is considered SELV and may be grounded or ungrounded.
- The circuitry of the converter may generate transients, which exceed the input voltage. Even if the input voltage is SELV (<60V) the components on the primary side of the converter may have to be considered as hazardous. A safety interlock may be needed to prevent the user from accessing the converter while operational. EMC Specifications Conducted Noise: The converters meet the requirements of level A and level B of EN55022, CISPR22 and FCC CFR title 47 Part 15 Sub -part J - Conducted (conducted noise on the input terminals) using the following circuit. C1 = 18nF for RFS04ZG & RFS06ZE C1 = 26nF for RFS06ZD, RFS06ZB & RFS06ZA C2 = 2µF to meet EN55022A C2 = 7µF to meet EN55022B Electromagnetic Susceptibility: Standard Applied Stress Class Level Performance Outcome * Electrostatic Discharge EN61000-4-2 2KV to pins B Electromagnetic Field EN61000-4-3 3V/m A Electrical Fast Transient EN61000-4-4 2000 Vp to input B Conducted Disturbances EN61000-4-6 3Vrms to input B * A denotes normal operation, no deviation from specification.

Failure to observe these instructions may result in failure or significant degradation of the module performance. Power - One will not honor any warranty claims arising from failure to observe these instructions. This product is approved for forced convection reflow soldering only. The curves below define the maximum peak reflow temperature permissible measured on Pins 1 and 10 of the converter. The lead -frame is constructed from a high temperature glass filled, UL94V0 flame retardant, diallyl ortho -phthalate moulding compound commonly used for packaging of electronics components. It has passed NASA outgassing tests and is certified to MIL -M-14. The coefficient of thermal expansion is equivalent to FR4. The gull wing lead s are formed to ensure optimal solder joint strength and structure. Furthermore they facilitate visual inspection (manual or automatic). The leads are formed from a 97% Cu alloy plated with Cu and Sn 90. This material is commonly used in the manufacture of integrated circuits. It has good corrosion resistance and exhibits the nobility inherent to all high copper alloys. Unlike brasses, this material is essentially immune to stress corrosion cracking. It also exhibits excellent solderability. It is re adily wetted by solders and performs well in standard solderability tests. (Dip of Class II or better). The product is manufactured with a patented process, which is fully automated, and ‘in -line’. This ensures that there is no contamination or mechanical stress on the lead -frame so that the co planarity and solderability are maintained. The product is shipped in JEDEC trays to guarantee preservation of the co -planarity and enable fully automated assembly in the final application. Pick & Place Assembly: The product is designed with a large flat area in the center of the top surface to serve as a pick up point for automated vacuum pick and place equipment. The ‘open board’ construction of the unit ensures that weight is kept to a minimum. However due to the relatively large size of th e component, a large nozzle (> 4 .0mm, depending on vacuum pressure) is recommended for picking and placing. The unit may also be automatically handled using ‘odd-form’ placement equipment , with mechanical grippers. For this type of equipment the end edges of the device, which have no leads and also feature the greatest dimensional accuracy, should be used as pick-up points.
