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.

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