Figure 25. Typical Application Circuit
The VCORE and VMAIN converter are always enabled in a typical application. The VCORE output voltage can
be disabled or reduced from 1.3 V to a lower, preset voltage under processor control. When the processor enters
the sleep mode, a high signal on the LOW_PWR pin initiates the change.
VCORE typically supplies the digital part of the audio codec. When the processor is in sleep or low-power mode,
the audio codec is powered off, so the VCORE voltage can be programmed to lower voltages without a problem.
A typical audio codec (e.g., TI AIC23) consumes about 20-mA to 30-mA current from the VCORE power supply.
