The peak current (sensed on the IS pin) is set by the voltage on FB pin. By comparing the voltage on FB pin and the IS ramp voltage, the duty-cycle of the PWM modulator is thus adjusted to provide the necessary load current at the desired output voltage. FB can be controlled by internal control circuit and external feedback circuit.
Function : Power Driver Integrated Full Digital Audio Amplifier
Package : MLP 48 Pin, 7 x 7mm

The device is a single chip full digital audio amplifier including power stage for stereo amplifier system. NTP-8230 is integrated with versatile digital audio signal processing functions, highperformance, high-fidelity fully digital PWM modulator, a stereo headphone amplifier and two high-power full-bridge MOSFET power stages. The NTP-8230 receives digital serial audio data with sampling frequency from 8kHz through 192kHz. It delivers 2 x 30 watts in stereo mode without heat sink.
The NTP-8230 has a mixer and Bi-Quad filters which can be used to implement the essential audio signal processing functions like loudness control, compensation of a loud speaker response and parametric equalization. All the functions of the NTP-8230 can be controlled by internal register values via I2C host interface bus. […]
