connection. Fixed resistors should have low temperature coefficient to minimize sensitivity to changes in temperature. A single resistor connected from the TRIM pin (pin 3) to the +Vout (pin 4), will decrease the output voltage which is shown in figure 1. A single resistor connected from the TRIM pin (pin 3) to the -Vout (pin 2) will increase the output voltage which is shown in figure 2. Accuracy of adjustment is subject to tolerances of resistors and factory adjusted output accuracy. Vout is equal to the desired output voltage. Figure 1.

Isolated 2W SM 2:1 Input Single Output DC/DC Converters KDC_MTC2.A01 Page 4 of 12 All enquiries: www.murata-ps.com/supportwww.murata-ps.com TECHNICAL NOTES ISOLATION VOLTAGE ‘Hi Pot Test’, ‘Flash Tested’, ‘Withstand Voltage’, ‘Proof Voltage’, ‘Dielectric Withstand Voltage’ & ‘Isolation Test Voltage’ are all terms that relate to the same thing, a test voltage, applied for a specified time, across a component designed to provide electrical isolation, to verify the integrity of that isolation. Murata Power Solutions MTC2 series of DC/DC converters are all 100% production tested at 3kVAC for 1 second and have been qualification tested at 5.2kVDC for 1 minute. A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?” The MTC2 series is pending recognition by Underwriters Laboratory to 250Vrms for Reinforced Insulation. REPEATED HIGH-VOLTAGE ISOLATION TESTING It is well known that repeated high-voltage isolation testing of a barrier component can actually degrade isolation capability, to a lesser or greater degree depending on materials, construction and environment. We therefore strongly advise against repeated high voltage isolation testing, but if it is absolutely required, that the voltage be reduced by 20% from specified test voltage. SAFETY APPROVAL ANSI/AAMI ES60601-1 The MTC2 series is pending recognition by Underwriters Laboratory (UL) to ANSI/AAMI ES60601-1 and provides 2 MOOP (Means Of Operator Protection) based upon a working voltage of 250 Vrms max, between Primary and Secondary. UL 60950 The MTC2 series is pending recognition by Underwriters Laboratory (UL) to UL 60950 for reinforced insulation to a working voltage of 250 Vrms. FUSING The MTC2 Series of converters are not internally fused so to meet the requirements of UL an anti-surge input line fuse should always be used with ratings as defined below. Input Voltage, 12V: 0.75A Input Voltage, 24V: 0.5A All fuses should be UL recognized and rated to at least the maximum allowable DC input voltage. CHARACTERISATION TEST METHODS Ripple & Noise Characterisation Method Ripple and noise measurements are performed with the following test configuration. C1 1μF X7R m ultilayer ceramic capacitor, voltage rating to be a minimum of 3 times the output voltage of the DC/DC converter C2 10μF tantalum capacitor, voltage rating to be a minimum of 1.5 times the output voltage of the DC/DC converter with an ESR of less than 100mΩ at 100 kHz C3 100nF multilayer ceramic capacitor, general purpose R1 450Ω resistor, carbon film, ±1% tolerance R2 50Ω BNC termination T1 3T of the coax cable through a ferrite toroid RLOAD Resistive load to the maximum power rating of the DC/DC converter. Connections should be made via twisted wires Measured values are multiplied by 10 to obtain the specified values.
