The TPA2092 is a Class D audio amplifier driver with integrated PWM modulator and over current protection. Combined with two external MOSFETs and a few external components, the TPA2092 forms a complete Class D amplifier with dual over current, and shoot-through protection, as well as UVLO protection for the three bias supplies. The versatile structure of the analog input section with an error amplifier and a PWM comparator has the flexibility of implementing different types of PWM modulator schemes.<\/p>\n

Loss-less current sensing utilizes RDS(on) of the MOSFETs.The protection control logic monitors the status of the power supplies and load current across each MOSFET. For the convenience of half bridge configuration, the analog PWM modulator and protection logic are constructed on a floating well. The TPA2092 implements start-up click noise elimination to suppress unwanted audible noise during PWM start-up and shut-down.<\/p>\n","protected":false},"excerpt":{"rendered":"
