9.4 Layout and Board Space

Careful board layout is necessary due to the high transient currents and switching frequency of the converter. All capacitors should be placed in close proximity to the device. A PCB layout proposal for a one-layer board is given in Figure 17. There is no specific EVM available for the TPS60204. However, the TPS60200EVM−145 can be used to evaluate the device.

The evaluation module for the TPS60200 can be ordered under product code TPS60200EVM−145. The EVM uses the layout shown in Figure 17. All components including the pins are shown. The EVM is built so that it can be connected to a 14-pin dual inline socket, therefore, the space needed for the IC, the external parts, and eight pins is 17,9 mm x 10,2 mm = 182,6 mm2.

IC1 TPS60204
C1, C2 Flying capacitors
C3 Input capacitors
C4 Output capacitors
C5 Stabilization capacitor for LBI
R1, R2 Resistive divider for LBI
R3 Pullup resistor for LBO
R4 Pullup resistor for EN

Capacitor C5 should be included if large line transients are expected. This capacitor suppresses toggling of the LBO due to these line changes.
