The control pin connects directly to the base of an internal transistor, and the switch off mechanism for the MTC1 works by forward biasing this NPN transistor. If the pin is left open (high impedance), the converter will be ON (there is no allowed low state for this pin), but once a control voltage is applied with sufficient drive current, the converter will be switched OFF. A suitable application circuit is shown below. MTC1S VIN R2 VC OV -VIN R1 D1 D1 (e.g. 1N4001) is required to provide high impedence when the signal is low. From the MTC1 specification, the drive current to operate this function is recommended to be 3mA to 8mA, and hence the value of R1 can be derived as follows: R1 = VC - VD - 0.6 IB Assuming VC=5V, VD=0.7V: CTRL Q1 R1= 5 - 0.7 - 0.6 = 732Ω (E96, 1% resistor) 5 x 10-3 For 5V TTL signal: Set R1 to be 82Ω or less Output Voltage Adjustment The MTC1S series has a trim capability which is located at pin 3, this allows the user to independently adjust the output voltages by ±10%. Adjustments to the output voltages can be accomplished via a single fixed resistor as shown in Figures 1 and 2. A single fixed resistor can increase or decrease the output voltage depending on its 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. TRIM DOWN TRIM UP Figure 1.

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 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 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 is pending recognition 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 at least the maximum allowable DC input voltage. 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.
