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 the output pins of the converter. Product Specifications Nov 2001 Output Current Limiting W hen the output is overloaded above the maximum output current rating, the voltage will start to reduce to maintain the output power 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, approximately every 25ms until the overload has cleared. Output Voltage Trim The trim feature allows the user to adjust the output voltage from the nominal. Output voltage can be adjusted by an external resistor. To increase Vo a resistor should be connected between pins 12 and 14. To decrease Vo a resistor should be connected between pins 12 and 13. To increase Vo: Rext = (A – (D x Vout)) / ( Vout – Vout.Nom) To reduce Vo: Rext = ((B x Vout) - C) / ( Vout.Nom - Vout) W here Vout is the desired output voltage Model NDS03ZA NDS03ZB NDS03ZD NDS03ZE NDS02ZG A 1945 2590 5010 7010 11260 B 1470 1730 2516 3161 4532 C 1944 2560 5010 7010 11240 D 470 750 1500 1500 1500 Shutdown Feature The remote control pin functions as a normal soft shutdown. It is referenced 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 requirements, Power-One limits maximum allowable case temperature (Tc) to 100°C (see Mechanical Drawings). Note: W hen 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. Parallel Operation Paralleling of two converters is not possible. 5-Nov-01 Rev 1.1 www.power-one.com Page 9 of 14 NDS Series: 10W / 3.0A DC/DC Converters 36-75V Input 1.5V, 1.8V, 2.5V, 3.3V and 5.0V Outputs 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 enduse 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) must 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 ( 3.0mm, 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.
