TYPICAL LAYOUT TC1301A

FIGURE 7-1:

MSOP8 Silk Screen Layer.

When doing the physical layout for the TC1301A/B, the

highest priority is placing the input and output

capacitors as close to the device pins as is practical.

Figure 7-1 above represents a typical placement of the

components when using SMT0805 capacitors.

FIGURE 7-2:

MSOP8 Wiring Layer.

A wiring example for the TC1301A is shown. The vias

represent the connection to a ground plane that is

below the wiring layer.

capacitor.

FIGURE 7-4:

DFN3X3 Top Metal Layer

Example.

Vias represent the connection to a ground plane that is

below the wiring layer.

Voltage Range

Table 8-1 describes the range of output voltage options

available for the TC1301A/B. VOUT1 and VOUT2 can be

factory preset from 1.5V to 3.3V in 100 mV increments.

The VDET (TC1301A) or threshold voltage (TC1301B)

can be preset from 2.2V to 3.2V in 10 mV increments.
