PRODUCT OVERVIEW
Offering configurable dual output voltages of +15V/-
10V, +20V/-5V and +15V/-5V, the MGJ6 series of
DC-DC converters is ideal for powering ‘high side’
and ‘low side’ gate drive circuits for IGBTs, Silicon
and Silicon Carbide MOSFETs in bridge circuits.
A choice of asymmetric output voltages allows
optimum drive levels for best system efficiency
and EMI. The MGJ6 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 MGJ6 protection features
include short circuit protection and overload
protection.

Synchronisation
100
The Disable/Synchronization pin has three modes:
1. When a dc logic low voltage is applied to this pin the MGJ6 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 MGJ6 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 MGJ6 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.
