Maximize power-device control efficiency with the right gate-driver power converter
(+15 volt/-5 volt, +15 volt/-9 volt, and +20 volt/-5 volt outputs) to support optimum drive levels with the highest system efficiency and minimal electromagnetic interference (EMI). The surface- mount packaging eases physical integration with the gate drivers and enables closer placement, thus reducing wiring complexity while minimizing EMI or radio frequency interference (RFI) pickup. The MGJ2series is specified for the high isolation and dV/dt requirements needed by bridge circuits used in motor drives
and inverters, and the industrial- grade temperature rating and construction provides long service life and reliability. Other key attributes include: ■ Reinforced insulation to UL62368 recognition (pending) ■ ANSI/AAMI ES60601-1 recognition (pending) ■ 5.7 kV DC isolation test voltage (per “hi pot” test)
■ Operation up to +105°C (with derating)
■ Short-circuit protection
■ Characterized common-mode transient immunity (CMTI) >200 kV/µs ■ Continuous barrier-withstand voltage of 2.5 kV ■ Characterized partial discharge performance Two units show the range of performance available in the MGJ2 series: ■ The MGJ2D152005MPC-R7 takes a nominal 15-volt input (13.5 to 16.5 volts) and delivers highly asymmetrical outputs of +20 volts and -5.0 volts at up to 80 mA each. Key specifications include 9% and 8% load regulation (maximum) for the two outputs (respectively), ripple and noise below 20/45 mV (typical/maximum), efficiency of 71/76% (minimum/typical), isolation capacitance of just 3 pF, and mean time to failure (MTTF) of approximately 1100 kilohours (kHrs) (determined using MIL-HDBK-217 FN2) and 43,500 kHrs (per Telecordia SR-332 calculation models).
