ICs for Audio Common Use AN7077Z Power supply and boost IC for class-H power amplifier s Overview A BTL 50 W × 2-channel (maximum. 75 W × 2channel) class-H power amplifier can be made up by combining the power supply boost amplifier AN7077Z and the single power supply BTL audio power amplifier AN7194Z, and it is possible to make a low consumption power system. 18.00±0.30 13.50±0.30 Unit : mm 4.00±0.20 1.50±0.10 φ3.60±0.10 • Incorporating various protection circuits • Built-in standby circuit • Peak detection circuit : Limits class-H operation at high frequency • Built-in timer circuit If a current larger than allowable value continues to flow into the power supply transformer, this circuit stops the class-H operation to prevent the transformer from damage by a fire.
