A choice of asymmetric output voltages allows optimum drive levels for best system efficiency and EMI. The MGJ3 series is characterised for high isolation and dv/dt requirements commonly seen in bridge circuits used in motor drives and inverters. A disable/frequency synchronisation pin simplifies EMC filter design. The MGJ3 protection features include short circuit protection and overload protection.

Murata Power Solutions MGJ3 series of DC-DC converters are all 100% production tested at 5.2kVDC for 1 second and 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?" When the insulation in the MGJ3 series is not used as a safety barrier , i.e. provides functional isolation only, continuous or switched voltages across the barrier up to 3kV are sustainable. Long term reliability testing at these voltages continues. Peak Inception voltages measured were in excess of 3.5kV when testing for partial discharge in accordance with IEC 60270. Please contact Murata for further information. The MGJ3 series has been recognised by Underwriters 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 MGJ3 series is recognised to ANSI/AAMI ES60601-1 and provides 1 MOPP (Means Of Patient Protection) and 2 MOOP (Means Of Operator Protection) based upon a working voltage of 250 Vrms max, between Primary and Secondary. UL 60950 The MGJ3 series has been recognised by Underwriters Laboratory (UL) to UL 60950 for reinforced insulation to a working voltage of 250Vrms with a maximum measured product operating temperature of 105C. Creepage and clearance 7mm. FUSING The MGJ3 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, 5V 2A Input Voltage, 12V 1A Input Voltage, 24V 0.5A All fuses should be UL recognised, 125V rated. CHARACTERISATION TEST METHODS Ripple & Noise Characterisation Method Ripple and noise measurements are performed with the following test configuration. C1 1F X7R multilayer ceramic capacitor, voltage rating to be a minimum of 3 times the output voltage of the DC-DC converter 10F 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 C2 than 100m at 100 kHz C3 100nF multilayer ceramic capacitor, general purpose R1 450 resistor, carbon film, 1% tolerance R2 50 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.

Min Disable/Sync1 Synchronisation Pull Down Current Input High Input Low Frequency Range Duty Cycle 2 0 90 25 Typ 0.5 100 Max 5 0.8 110 75 Units mA V V kHz % The Disable/Synchronization pin has three modes: 1. When a DC logic low voltage is applied to this pin the MGJ3 is disabled and enters a low quiescent current sleep mode. 2. When this pin is left floating or a DC logic high (CMOS/TTL compatible) voltage is applied the MGJ3 is enabled and operates at the programmed frequency of 100kHz. 3. When a square wave of between 90kHz and 110kHz is applied to this pin, the switcher operates at the same frequency as the square wave. The falling edge of the square wave corresponds to the start of the switching cycle. If the signal is slower than 25Hz, it will be interpreted as enabling and disabling the part. If the MGJ3 is disabled, it must be disabled for 7 clock cycles before being re-enabled. Note: The DIS/Sync pin is a high impedance TTL input and can be triggered by noise from external circuits if not treated carefully. It is advised that any pcb traces connected to the DIS/Sync pin are kept as short as possible and away from other noisy pcb traces. The track should follow a similar route to the return path to avoid differential noise pick up. If the pin is not used for synchronisation then a 22nF capacitor can be added from DIS/Sync pin to -Vin to suppress noise.

If a high dv/dt above 80kV/us is expected from output to input it is advised that a common mode filter is used on the input without Y capacitors. This will reduce the common mode current and reduce interference with primary side circuits.
