Use the
following guidelines to set up the equipment:
- Set power supply #1 for 20 VDC,
8A current limit and then turn off the supply.
- Connect the output of power
supply #1 in series with a current meter to J1 (VIN and PGND).
- Connect a voltage meter across J1
(VIN) and J1 (PGND).
- Connect load #1 in series with a
current meter to J3 (VOUT and PGND).
- Connect a voltage meter across J3
(VOUT and PGND).
- Set electronic load to CC mode at
4A. Turn off load #1.
- Connect J5 to the EV2400. Connect
J5 to the I2C PORT 2 on the EV2400.
- Make sure the jumpers are
installed as indicated in IO and Jumper Descriptions.
- Turn on the computer and power
supply #1. Open the bqStudio software.
- Select Charger and
click the Next button.
- Select
Charger_2_00_BQ25758.bqz on the Select a Target
Page.
- After selecting the
target device, click Field View and then click the Read
Register button.
- Set WATCHDOG to disabled.
- In 16 Bit Registers,
VOUT_REG default is 5000mV
- Buck Test: Set
VOUT_REG to 5V (5000mV) and then turn on load #1, measure
V(J1(VAC)) = 20V ± 0.5V
I(J1(IAC)) = 1A ±
0.5A
V(J3(VOUT)) = 5V ± 0.5V I(J3(IOUT)) = 4A ±
0.5A
- Buck-Boost Test:
Set VOUT_REG to 20V (20000mV), measure
V(J1(VAC)) = 20V ± 0.5V
I(J1(IAC)) = 4A ±
0.5A
V(J3(VOUT)) = 20V ± 0.5V I(J3(IOUT)) = 4A ±
0.5A
- Boost Test: Set
VOUT_REG to 36V (360000mV), measure
V(J1(VAC)) = 20V ± 0.5V
I(J1(IAC)) = 7.2A ±
0.5A
V(J3(VOUT)) = 38V ± 0.5V I(J3(IOUT)) = 4A ±
0.5A
