TS3310DB

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.
