FTM / Motor Control / Murata — MGN1 DC-DC Converter Modules
Murata has introduced compact new 1 W dc-dc converters, the MGN1 series, which supply the voltages needed by the gate drivers of wide bandgap gallium nitride (GaN) power switches. The regulated output-voltage options are +8 V, +12 V, and +6/-3 V from a 12 V nominal input voltage.
Lightweight, and measuring 12.0 mm x 16.0 mm x 4.25 mm, these surface-mount modules can easily be integrated into space-constrained designs.
One of the key attributes of the MGN1 series converters is their ultra-low isolation capacitance of 2.5 pF. This minimizes the coupling of transients across the isolation barrier, preventing signal distortion, and alleviating system EMI problems.
Common-mode transient immunity of more than 200 kV/µs makes the MGN1 modules ideal for GaN-based systems that switch at high frequency. Thanks to their partial discharge performance, reliable operation is maintained in high-voltage conditions.
The dc-dc converters in Murata’s MGN1 series support a continuous isolation barrier withstand voltage of 1.1 kV. UL 62368 conformance is pending for 650 V dc basic insulation and 240 V ac reinforced insulation.
