APPLICATION INFORMATION
switching frequency
The switching frequency is determined using the values of the components connected to ROSC (pin 13) and
COSC (pin 14) and are calculated using Equation 9.

COSC
The switching frequency was chosen to be centered on 250 kHz. This frequency represents the optimization
of audio fidelity due to oversampling and the maximization of efficiency by minimizing the switching losses of
the amplifier.
The recommended values are a resistance of 120 k
Ω and a capacitance of 220 pF. Using these components
values, the amplifier operates properly by using 5% tolerance resistors and 10% tolerance capacitors. The
tolerance of the components can be changed as long as the switching frequency remains between 200 kHz and
300 kHz. Within this range, the internal circuitry of the device provides stable operation.
