Functional Descriptions System Standby The bias levels are turned on and off under control of the high/low state of the STBY pin. When the STBY pin is low, the bias levels will be turned off, and when that pin is high, the bias levels will be applied. Mute Function The mute function is provided mainly to mute the output so that impulse noise will not appear in the output when the power supply is being turned on. (1) Output Muting The output PWM signal can be turned on or off by setting the MUTE pin high or low. When the MUTE pin is low, the internal oscillator is stopped. This oscillator operates at all times that the MUTE pin is high. (2) Power On Sequence Applications should provide a power-on muting period of at least 500ms to minimize impulse noise.

MUTE pin capacitor voltage
Output pin Turn-on time Amplifier on
Turn-on time : the time between the point the STBY pin is set high and the point the MUTE pin is set high.
(3) Power Down Sequence Applications should provide a power down muting period of at least 100ms to minimize impulse noise.
