International Rectifier's IRS20965 Digital Class D Audio Driver IC with protected Pulse Width Modulation (PWM) switching and a full complement of audio MOSFETs is optimized for high performance Class D audio amplifier applications. The IRS20965 features high-side and low-side independent floating PWM input to allow deadtime control from an external PWM controller. Shoot-through prevention logic provides additional safety in the event of PWM controller failure. The new IC also features over-current sensing output and 2A gate drive output capability. Operating up to 800kHz, other key features of the IRS20965 include programmable bidirectional over-current detection with self-reset function, high noise immunity, ±100 V ratings to deliver up to 500W in output power and 3.3V / 5V logic compatible input.
IR's IRG7PK35UD1 IGBT is co-packaged with an ultra-low forward voltage diode, and utilizes IR's Gen7 thin-wafer trench technology to deliver extremely low VCE(ON) and ultra-fast switching. This allows for superior conduction and switching losses for high system efficiency in induction heating applications. Expanding the voltage range of the device to 1400V enables the design of higher power single-ended parallel resonant power converters and offers additional guard band for more robust designs. The IRG7PK35UD1 extends the power range of induction heating systems.
International Rectifier IR25750L current sensing IC extracts the VDS(on) of a power MOSFET, or the VCE(on) of an IGBT, during the switch on-time. IR's proprietary 600V HVIC technology then blocks the high drain voltage to during the MOSFET or IGBT off-time. This IC allows for external current sensing resistors to be eliminated for reducing power losses and increasing overall system efficiency. The IC includes a gate drive input that provides VCC supply voltage to the IC and synchronizes the internal sensing circuit to the on and off times of the switch. Programmability and temperature compensation are also possible.
International Rectifier IR3720 power monitor ic with digital interface measures the output voltage and inductor current of low-voltage DC-to-DC converters and reports the average power over a user specified time interval as a digital word on the I²C. The output current is measured across a current sensing resistor or indirectly across the inductor's DCR winding resistance. Additionally, the current measurement method is also applicable to multiphase converters. The real time voltage and current signals are multiplied, digitized, and averaged over a user selectable averaging interval providing Patent Pending TruePower™ measurement of highly dynamic loads.

International Rectifier's IRS2983S LEDrivIR™ is a fully integrated, fully protected SMPS control IC designed to drive Flyback converter LED drivers. The IRS2983S features include primary side power regulation, which allows a basic converter to be implemented without the need for an opto isolator in a Flyback LED driver with a fixed load enabling a low cost, high reliability isolated LED driver design to be realized. The IRS2983S may also be used in converters that do include secondary feedback through an opto isolator. Other features of the IRS2983S include a high voltage startup enabling VCC supply to be derived initially from the high voltage DC bus until the auxiliary inductor winding is able to take over. The IRS2983S operates in critical conduction (CrCM) or discontinuous (DCM) modes and is fully protected against open and short circuit as well as inductor saturation. The IRS2983S may be used in single stage Flyback LED drivers with an unsmoothed DC bus to obtain high power factor and low THD.
