10.1 Power Supplies
The TAS2564 requires four power supplies:
- Boost Input (terminal: VBAT)
- Voltage: 2.9 V to 5.5 V
- Max Current: 5 A for ILIM = 4.0 A (default)
- Analog Supply (terminal: VDD)
- Voltage: 1.65 V to 1.95 V
- Max Current: 30 mA
- Internal Supplies
- Digital Supply (terminal: DREG): 1.35 V to 1.65 V
- Boost Output (terminal: VBST) : VBAT to 13V
- Class-D Power Supply (terminal: PVDD): Short to VBST
The decoupling capacitors for the power supplies should be placed close to the device terminals.
