D1 (e.g. 1N4001) is required to provide high impedence when the signal is low. 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 1W SM 2:1 Input Single Output DC/DC Converters KDC_MTC1.C01 Page 4 of 11 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 MTC1 series of DC/DC converters are all 100% production tested at their stated isolation voltage. This is 3kVRMS for 1 second. A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?” The MTC1 series has been recognized by Underwiters Laboratory to 250 Vrms Reinforced Insulation, please see safety approval section below. 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 MTC1 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 MTC1 series has been recognised by Underwriters Laboratory (UL) to UL 60950 for reinforced insulation to a working voltage of 250 Vrms. FUSING The MTC1 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: 0.5A Input Voltage, 24V: 0.25A All fuses should be UL recognized and rated to 125V. RoHS COMPLIANCE INFORMATION, MSL This series is compatible with RoHS soldering systems with a peak reflow solder temperature of 245ºC as per J-STD-020D.1. The pin termination finish on this product series is Gold with Nickel Pre-plate. The series is backward compatible with Sn/Pb soldering systems. The series has a Moisture Sensitivity Level (MSL) 1. CHARACTERISATION TEST METHODS Ripple & Noise Characterisation Method Ripple and noise measurements are performed with the following test configuration.
