TEST SET-UP AND OPERATION

1. Visually inspect that jumpers from the Vin pin are connected to pins SD (Shut Down), PWM and SYNC (Synchronization).

*2.Attach an electronic load set to either resistive or current mode between Vout pin and GND pin on the demo board. Set

*3.Attach a dc power supply, with at least 3A current capability between the Vin to the GND pins on the demo board. The

4. Connect an oscilloscope GND to the GND pin, and the channel -1 probe to the Vout pin. Set the scope to 20MHz Band-

5. In order to test the DB in PSM, adjust the load to 20mA. Then cut the jumper of the PSM and connect it to the GND.

6. The synchronization of the external clock is easily accomplished by connecting the external clock into the SYNC pin.

*Note: The testing wires connected to the Vin, Vout and GND pins must have a minimum cross section of 2.5mm

the load current to 200mA or equivalent resistor value. After the converter is powered-up, output load current can be

adjusted between 0 to 600mA (items 1 - 5), 0 to 1000mA (items 6 - 8), 0 to 1500mA (items 9 - 11; 19), 0 to 2000mA (item 20)

0 to 2500mA (items 12 - 14) and 0 to 3000mA (items 15 - 18).

input voltage can be adjusted as written in the attached table.

Width limit and than set the coupling to AC. The waveform that appears is the ripple measurement.

Logic high to low transition synchronizes the clock. The external clock frequency must be within 1.2 to 1.5 times the

internal clock frequency. (If not used, the SYNC pin must be connected to Vin pin).

FEATURES

• FunctionPAK is a synchronous Buck or a Boost converter

• The Buck DB is available at Vout = 1.8v or 2.7v or 3.3v and

• The FunctionPAK is available at Vout = 1.5v to 3.6v for the

• The PWM/PSM pin can be used to program the converter

• PWM is the normal pulse width modulation that keeps the

output regulated through the load range, while the PSM

mode offers better efficiency at light load to conserve

power by skipping switching pulses. Notice the PSM only

gain efficiency advantage at light load and can only deliver

certain load current before output drops out of regulation.
