International Rectifier, (IR) has released the IRS2093 driver IC for high performance Class D Audio applications from 50 to 150 W, including home theater systems and car audio amplifiers. Based upon a half bridge topology, the IRS2093 integrates four channels of high-voltage, high performance Class D audio amplifier drivers with PWM modulators in a single IC. Housed in a compact MLPQ48 package, the IC shrinks board size by an additional 50% when compared to previous offerings. The IRS2093 offers error amplifier, PWM comparator, gate driver, and robust protection circuitry. In addition 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.
