8.4.4 Boost

The TAS2564 internal processing algorithm automatically enables the boost when needed. A look-ahead algorithm monitors the battery voltage and the digital audio stream. When the speaker output approaches the battery voltage the boost is enabled in-time to supply the required speaker output voltage. When the boost is no longer required it is disabled and bypassed to maximize efficiency. The boost can be configured in one of two modes. The first is low in-rush (Class-G) supporting only boost on-off and has the lowest in-rush current. The second is high-efficiency (Class-H) where the boost voltage level is adjusted to a value just above what is needed. This mode is more efficient but has a higher in-rush current to quickly transition the levels. This can be configured using Table 83.

BST_MODE[1:0] BOOST MODE
00 Class-H - High efficiency (default)
01 Class-G - Low in-rush
10 Always On
11 Always Off - Pass-through

The boost can be enabled and disabled using BST_EN register. When driving the Class-D amplifier using an external supply through the PVDD pin, the boost should be disabled and the VBST pin can be left floating. Do not drive an external voltage on the VBST pin. When suppling and external PVDD voltage the VBAT voltage must also be supplied to the device. While VBAT supply must be present it will not carry current to the speaker load.

The boost has a soft-start to limit in-rush current during the initial charge. The current limit and soft-start timer are configurable to adjust to system component selection.

The boost inductor and decoupling capacitor range needs to be specified using BST_IR and BST_LR registers. These setting optimize the boost to ensure current limit accuracy and avoid clipping in class-H operation.

Table 87. Boost Inductor Range

BST_IR[1:0] INDUCTANCE (H)
00 < 0.6 µH
01 0.6 µH-1.3 µH (default)
10 1.3 µH - 2.5 µH

Table 88. Boost Load Regulation

BST_LR VALUE
00 4.4A/V; load regulation = 0.9 V
01 3.67 A/V; load regulation = 1.1 V
10 2.93 A/V; load regulation = 1.37 V
11 1.95A/V; load regulation=2.06V

The maximum boost voltage regulation is set by BST_VREG. When operating in class-G mode the boost when needed will be at this voltage. In class-H mode of operation the boost voltage is automatically selected based on the audio signal but, will not exceed this set value.

The peak current limits the boost current drawn from the VBAT supply. This setting allows flexibility in the inductor selection for various saturation currents. The current limit can be adjust in 45 mA steps with register BST_ILIM[5:0]. The peak current limit setting is the maximum and may be temporarily reduced if the and ICLA current limit is active.
