IRS2461SXUMA1

IRS2461SXUMA1 is a 400V Class D audio amplifier controller. The IRS2461S integrates high voltage, high performance Class D audio amplifier drivers with PWM modulator and protection. In conjunction with external MOSFET, the IRS2461S forms a single channel Class D audio amplifier. The IRS2461S is designed with floating analogue inputs and protection control interface pins convenient for half bridge applications. High and low side MOSFETs are protected from over current conditions by a programmable over current protection. Essential elements of PWM modulator section allow flexible system design.
