Suited for use in Class-D audio amplifiers, Model MD7120 provides 12-200 V output, Â±5 nanosec asleep time matching, and acceleration or abatement time of beneath than 30 nsec with archetypal 1 nF load. Unit can be affiliated anon to 200 V accumulation voltage to drive over 100 W achievement with 90% efficiency. Its centralized amount consists of ascendancy logic, akin translators, bootstrap-powered aerial ancillary aboideau driver, and over-temperature, under-voltage, and accepted aegis circuits.
MD7120 Appearance Up To 200V Arch Accumulation Voltage and Over 90% Efficiency
SUNNYVALE, Calif., June 24, 2008- Supertex (NasdaqGS: SUPX), a accustomed baton in aerial voltage analog and alloyed arresting chip circuits (ICs), today alien the MD7120, a aerial voltage, aerial speed, N-channel, full-bridge ability MOSFET disciplinarian for use in Class-D audio amplifiers. The MD7120 provides a ample ambit of achievement voltage from 12V to 200V, has ±5 nanosecond asleep time analogous and acceleration or abatement times of beneath than 30 nanoseconds with a archetypal 1nF load. The N-channel MOSFETs are apprenticed from accustomed argumentation akin inputs by anon accompanying centralized akin translators.
The MD7120 can be affiliated anon to a 200V accumulation voltage and can drive over 100W achievement with 90% efficiency. Its centralized amount consists of ascendancy logic, akin translators, a bootstrap-powered aerial ancillary aboideau disciplinarian and over-temperature, under-voltage and accepted aegis circuits. The thresholds of the accepted aegis for both the aerial and low abandon are resistor-programmable.
“The MD7120 has been optimized for ambit analytical to Class-D audio achievement such as aerial ability and low EMI,” states Ahmed Masood, Vice President of Marketing for Supertex. “Additionally, this MOSFET disciplinarian provides up to a 3.0A aiguille active accepted with akin achievement attrition and channel-to-channel advancement adjournment for lower absolute harmonic baloney and noise.”
The MD7120 is accessible in a 32-lead QFN amalgamation (MD7120K6-G). The allotment is Green and RoHS compliant. Samples are accessible from stock. Lead-time for assembly quantities is 4-6 weeks ARO. Pricing is US $5.20 anniversary for the MD7120K6-G in 1K quantities.
