Introduction
The TPS65560 is a highly integrated flyback converter used to charge photo flash capacitors. The Texas
Instruments TPS65560EVM-165 evaluation module (EVM) helps designers evaluate the operation and
performance of this device.
The EVM contains one fully functional photo flash charger capable of charging a photo flash capacitor to
320 volts from a battery with voltage between 1.6 and 12 volts. The EVM also provides a flash lamp and
trigger circuit to help the designer evaluate the charging characteristics. The onboard lamp circuit can be
disabled so that the EVM can be connected to a user-supplied lamp and trigger circuit.

Page 2: Setup
This section describes the jumpers and connectors on the EVM as well as how to properly connect, set up, and use the TPS65560EVM-165. WARNING The TPS65560EVM-165 produces high voltage and is designed to charge the bulk flash capacitor to more than 320 volts. This capacitor can maintain this voltage for a long time, even after the input power has been removed from the board. - Page 3 10.

Page 5: Board Layout
Figure 4 show the board layout for the TPS65560EVM-165 PCB. The nodes with high-switching frequencies and currents are kept as short as possible to minimize trace inductance. Careful attention has been given to the routing of high-frequency current loops and a single-point grounding scheme is used for all high-current and high-voltage traces. -
