Using the TPS62102 Low-Power High-Efficiency Buck Converter Evaluation Module
4
Operating Instructions
4.1
Connect a dc Power Supply to Terminal TB1
The power supply should be capable of supplying up to 10 V at 0.5 A. The power supply should
be set to its minimum output voltage level and current limited to 0.5 A.
4.2
Connect the Load to TB2
This load should be capable of handling 0.5 A at 3.5 V.
4.3
Place a Jumper on CB2
Placing the jumper from pin 1 to pin 2 pulls SD/SYNC high, resulting in converter shutdown.
·
Placing a jumper from pin 2 to pin 3 pulls SD/SYNC low, resulting in normal operation.
4.3.1
Placing a jumper on CB1 is optional.
A jumper from pin 1 to pin 2 sets MODE high, forcing the converter into the
constant-frequency, heavy-load mode.
A jumper from pin 2 to pin 3 sets MODE low, forcing the converter into the pulsed-variable
low power mode.
Letting MODE float, not using a jumper on CB1, allows the converter to operate in
auto-mode, the output load detector circuitry determines if the converter should be running in
the constant-frequency or pulsed-variable frequency mode.
4.4
Turn on the Electronic Load
Adjust the load to operate between 10 mA and 500 mA.
4.5
Turn on the Input Power Supply
Starting with the input dc power supply at its minimum setting, slowly increase the voltage to
7 V
±
0.5 V.
4.6
Shut Down the Converter
To shut down the converter, decrease the dc input power supply voltage to zero. Turn off the
electronic load.
