APPLICATION INFORMATION
power dissipation (continued)
PDISS must be less than that allowed by the package rating. The thermal resistance junction to ambient of the
used 10-pin MSOP is 294
°C/W for an unsoldered package. The thermal resistance junction to ambient with
the IC soldered to a printed circuit using a board layout as described in the application information section, the
RΘJA is typically 200°C/W, which is higher than the maximum value calculated above. However in a battery
powered application, both VI and TA will typically be lower than the worst case ratings used in equation 6 , and
power dissipation should not be a problem in most applications.
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 20.
An evaluation module for the TPS60200 is available and can be ordered under product code
TPS60200EVM–145. The EVM uses the layout shown in Figure 20. 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 8 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.
