Overview

The MGJ2D122005SC is a 2W isolated DC-DC converter specifically engineered for powering gate drive circuits in high-side and low-side switch applications. It provides asymmetric dual output voltages of 20V and -5V from a nominal 12V input, which is ideal for optimal IGBT and MOSFET switching. Featuring 5.2 kV high isolation, it ensures reliable operation in high-voltage bridge circuits.

Why Choose This Part

This module offers a high isolation barrier of 5.2 kV, making it suitable for high-reliability medical and industrial environments. Its asymmetric outputs are specifically tuned to maximize gate drive efficiency, reducing the need for external voltage regulation components in the drive stage.

Applications

IGBT Gate Drive Power
Provides the necessary asymmetric rail voltages to ensure fast turn-on and robust turn-off of IGBT modules in motor inverters.
SiC MOSFET Driving
The 20V/-5V output configuration supports the specific gate voltage requirements for Silicon Carbide MOSFETs to minimize switching losses.
High-Voltage Bridge Circuits
Suitable for powering high-side gate drivers in H-bridge and 3-phase inverter topologies due to its high 5.2 kV isolation rating.
Industrial Motor Control
Integrated into industrial frequency converters and AC drives where galvanic isolation between control logic and power stages is required.

Getting Started

When integrating this SIP module, ensure a low-impedance path for the output capacitors to handle the high peak currents typical of gate drive switching. No external controller is required, but a 10uF input capacitor is recommended to minimize reflected ripple current back to the 12V supply.
