MPQ18913 5-30V High-Frequency Transformer Driver QFN-10

MPQ18913 5-30V High-Frequency Transformer Driver QFN-10

The MPQ18913 is a high-frequency half-bridge transformer driver.

Key Specifications

Features

• Low EMI: o Soft Switching o Flip-Chip Package o Low Interwinding Capacitance
• Small Solution Size: o 400kHz to 5MHz Configurable Switching Frequency (fSW) o Available in a Tiny QFN-10 (2mmx2.5mm) Package with Wettable Flanks

Typical Application Circuit

Applications

• Silicon Carbide (SiC) Transformer Driver Biased Supplies
• Automotive Traction Inverters and Onboard Charging (OBC)
• DC Fast-Charging Stations
• Uninterrupted Power Supplies (UPSs) and Solar Inverters

Design Notes

• The isolation rating is only valid if the PCB keeps the required creepage and clearance across the barrier — the package alone does not guarantee it.
• Common-mode transient immunity matters more than DC withstand in motor and gate-drive applications; check the dV/dt figure.
• Decouple both sides independently, with the capacitor returned to that side's ground.
• Propagation delay and pulse-width distortion set the timing margin in a closed loop.
