DESCRIPTION
The EV2696A-Q-00B is an evaluation board for
the MP2696A, a high-integrated, flexible switch-
mode battery charge management and system
power path management device.
The MP2696A has three operation modes:
charge mode, boost mode and sleep mode.
In charge mode, EV2696A-Q-00B achieves up
to 3.6A charge current with a 5V input source.
In boost mode, EV2696A-Q-00B achieves up to
6.5A peak inductor current to deliver a 5V SYS
output.
All the parameters and control can be easily
accessed via the I2C interface.

QUICK START GUIDE
1. Please install USB dongle driver on the computer, and connect the dongle to the SCL/GND/SDA
connector on the EVM
2. Connect the battery pack to TP1/BATT and TP2/GND connectors, take care of that the battery
positive/negative terminal must not be reverse connected.
3. If using a battery emulator, preset the battery emulator to 3.8V/5A and turn off the emulator, connect
to TP1/BATT and TP2/GND, then turn on the emulator output.
4. Verify the USB dongle successfully connects the MP2696A to the computer (no warning shows on
the top of the GUI).
5. Now the charging and boost parameters can be controlled by the GUI interface.
