The MD7120 can be connected directly to a 200V supply voltage and can drive over 100W output with 90% efficiency. Its internal core consists of control logic, level translators, a bootstrap-powered high side gate driver and over-temperature, under-voltage and current protection circuits. The thresholds of the current protection for both the high and low sides are resistor-programmable.
"The MD7120 has been optimized for parameters critical to Class-D audio performance such as high efficiency and low EMI," states Ahmed Masood, Vice President of Marketing for Supertex. "Additionally, this MOSFET driver provides up to a 3.0A peak driving current with matched output resistance and channel-to-channel propagation delay for lower total harmonic distortion and noise."
The MD7120 is available in a 32-lead QFN package (MD7120K6-G). The part is Green and RoHS compliant. Samples are available from stock. Lead-time for production quantities is 4-6 weeks ARO. Pricing is US $5.20 each for the MD7120K6-G in 1K quantities.
