USING THE EVALUATION BOARD
1) Powering Up the SP4446 Circuit
The SP4446 Evaluation Board
can be powered from inputs from a +1.2V to +7.0V. Connect
with short leads directly to the “Vin” and “Gnd” posts. Monitor the Output Voltage and connect
the Load between the “Vout” post and the 2
nd
“GND” post.
2) Using the J1 Jumper: Enabling the SP4446 Output and using the Shutdown Mode
The SP4446 output will be Enabled if the J1 Jumper is in the top or pin 1 to 2 position. If J1 is
in the pin 2 to 3 position, the Shutdown pin is brought to GND, which puts the SP4446 in the low
quiescent Shutdown Mode.
3) Selecting the Inductor
In selecting an inductor, the saturation current specified for the inductor needs to be greater
then the SP4446 peak current to avoid saturating the inductor, which would result in a loss in
efficiency and could damage the inductor. The SP4446 evaluation board uses a Murata 10uH
inductor with an Isat value of 450mA and a DCR of 0.39ohms, which easily handles the Ipeak of
350mA of the SP4446 and will deliver high efficiencies. Other inductors could be selected
provided their Isat is greater than the Ipeak of the SP4446.
