Setup; J5 Pinout - Texas Instruments TPS65560EVM-165 User Manual

Setup

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.
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. Do not touch any
exposed metal on the TPS65560EVM-165 without first discharging
the bulk flash capacitor.
2.1 Input / Output Connector Descriptions
2.1.1 J1 – Vbatt
This is the positive battery voltage input connection to the converter. This voltage should be between 1.6
and 12 volts dc.
2.1.2 J2 – GND
This is the return connection for the battery voltage to the converter.
2.1.3 J3 –V
CC
This is the positive digital voltage supply. This voltage should be between 2.7 and 4 volts dc.
2.1.4 J4 – GND
This is the return connection for the digital voltage supply.
2.1.5 J5 – REMOTE CONTROL
This connector is used to interface the EVM to a personal computer as an optional method of controlling
the EVM. All necessary control inputs and outputs for the converter are present on this connector. The
flash and charge signals are inverted before connecting to the TPS65560 on the EVM board. The pinout
for the connector is shown
