DALLAS, TEXAS 75265
APPLICATION INFORMATION
TPS6734 converter design with recommended layout
The following schematic (Figure 13) and a required-components table are provided for a 12-V-output boost
converter. The converter is capable of delivering 120 mA of output current over an input voltage range of 3.75 V
to 12 V. Recommended layout and detailed artwork for a PCB are provided in Figures 14 through 17.
NOTE A: A jumper between pins P1-3 and P1-4 shuts off the TPS7634. Remove the jumper to resume normal operation.
