QUICK START PROCEDURE
Required Equipment
TS3310DB
1.2V Battery or 1.2V Power Supply
Three Digital Multimeters
One Oscilloscope
To evaluate the TS3310 the following steps are to be
performed:
1) Connect the battery or power supply’s positive
terminal to the test point labeled IN. Connect the
negative terminal of the battery or power supply
to the test point labeled GND.
2) To monitor the STORE output voltage, connect
the positive terminal of the voltmeter to the test
point labeled STORE. Connect the negative
terminal of the voltmeter to the test point labeled
GND. The output voltage should be
approximately 3V.
3) To monitor the STORE output voltage ripple,
connect an Oscilloscope probe to the test point
labeled STORE.
4) To monitor the OUT output voltage, connect the
positive terminal of the second voltmeter to the
test point labeled OUT. Connect the negative
terminal of the voltmeter to the test point labeled
GND. The output voltage should be
approximately 3V. To disable the OUT output
voltage, set jumper OUT_ON to LOW.
5) To monitor the open-drain VGOOD output,
connect an Oscilloscope Probe to the test point
labeled PG. The VGOOD output signal assumes
a high impedance once the STORE output
voltage is greater than 90% of the target output
voltage, which is 2.7V for the 3V default
configuration.
6) The maximum STORE output current for the
TS3310 programmed for 3V output operation with
a 1.2V input voltage can be measured. To
evaluate the maximum STORE output current for
the TS3310-10DB, configured for 10µH
operation, connect a 75Ω resistor from STORE to
GND.
7) To measure the STORE output current, connect
an Ammeter in series between the 75Ω Resistor
and GND.
8) To evaluate the TS3310 with a different output
voltage setting, reconfigure the provided jumpers
S0-S2. Please refer to Table 2 for the available
output voltages and their corresponding S0-S2
jumper configuration. Note that the input voltage
range is 0.9V to 3.6V. For 5V output operation, a
minimum input voltage of 2V is required.
