The new IRS2093 is housed in a compact MLPQ48 package that shrinks the board size by a further 50% compared to previous offerings.
“With the addition of an external MOSFET and passive components, a complete four channel Class D audio amplifier can be realized in a 50% smaller footprint, delivering the efficiency and size advantages of Class D while providing the high audio performance traditionally associated with Class AB solutions,” stated Jun Honda, International Rectifier’s systems engineering manager, Energy Saving Products Business Unit.
The new IRS2093 provides error amplifier, PWM comparator, gate driver, and robust protection circuitry. Additionally, the new 200V device features an analog PWM modulator with frequency up to 800 kHz, programmable bidirectional over-current protection (OCP) with self-reset control, under-voltage lockout protection (UVLO), and programmable preset deadtime for a scalable power design.
The new IC may be co-designed with International Rectifier’s wide range of digital audio MOSFETs addressing output power from 50W to 150W. These MOSFETs have been optimized around parameters critical to audio performance like efficiency, THD, and EMI.
The IRAUDAMP8 reference design, featuring the new IRS2093 is also available.
