TPS65560EVM-165

This user’s guide describes the characteristics, operation, and use of the TPS65560EVM-165 Evaluation
Module (EVM). This EVM demonstrates the Texas Instruments TPS65560 Integrated Photo Flash
Chargers with IGBT Drivers. This user’s guide includes setup instructions, a schematic diagram, a bill of
materials, and printed-circuit board layout drawings for the evaluation module.

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.
