SLVU319 - July 2009 Submit Documentation Feedback TPS55332EVM 1 Setup 2 www.ti.com Setup This section describes the jumpers and connectors on the EVM as well and how to properly connect, set up and use the TPS55332EVM. 2.1 Input/Output Connector Description J1 - Input is the power input terminal for the converter. The terminal block provides a power (Vbat) and ground (GND) connection to allow the user to attach the EVM to a cable harness. J2 - Output is the regulated output voltage for the converter. The terminal block provides a power (VOUT) and ground (GND) connection to allow the user to attach the EVM to a cable harness. J3 - Sync is the input terminal for an optional external input clock to the converter. The external clock can be used to synchronize the switching frequency for multiple devices. The external clock frequency must meet the Fsw<Fext<2xFsw guideline, if used. JP1 - Enable is the jumper used to enable the converter. The converter will be enabled when the Enable is high and disabled when low. The jumper placement allows the converter to be enabled or disabled. ENA ENA disabled enabled Figure 1. Enable Jumper Settings 2.2 Setup The input voltage range for the converter is 3.6 volts to 24 volts. A load should be applied to the Output terminal for proper operation. 2.3 Operation For proper operation of the TPS55332, JP1 should be properly configured. The recommended setting, using shorting blocks. JP1 to Enabled In this configuration, the device will power up when power is applied. 2.4 EMC Filter The EVM has a pi filter input stage to provide improved EMC performance. A reverse battery protection diode, D2, is also installed. The diode and pi filter are not required for normal operation of the boost regulator. 3 Board Layout Figure 2, Figure 3 and Figure 4 show the board layout for the TPS55332EVM PWB. A jumper is provided to Enable the device. The TPS55332 are high efficiency, but does dissipate power. The PowerPADTM package offers an exposed thermal pad to enhance thermal performance. This must be soldered to the copper landing on the PCB for optimal performance. The PCB provides 2 oz copper planes on the top and bottom to dissipate heat. 2 TPS55332EVM SLVU319 - July 2009 Submit Documentation Feedback Board Layout www.ti.com Figure 2.

Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are questions concerning the input range, please contact a TI field representative prior to connecting the input power. Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the EVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than 85C. The EVM is designed to operate properly with certain components above 85C as long as the input and output ranges are maintained. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during operation, please be aware that these devices may be very warm to the touch.
