Figure 1. SP6650 Evaluation Board Schematic
The SP6650 Evaluation Board provides conve-
nient test points to connect the input to Power
Supply or Li-Ion Battery. The Input and Output
connections are made with raised female pin
receptacles which can accommodate easy-hook
connection leads for power and meter connec-
tions, as well as scope probe hooks and grounds
for waveform measurements.
USING THE EVALUATION BOARD
1) Powering Up the SP6650 Circuit
The SP6650 Evaluation Board
can be powered
from a single Li-Ion battery or a +2.7 to +6.5V
power supply. Connect with short leads directly
to the “V
IN
” and “GND” posts. Note the SP6650
will remain in “shutdown” until pin 2 of the
Jumper J2 is applied to the GND.
2) I LIM Programming
Connect pin 4 of the SP6650 to V
IN
for 0.8 A
peak Inductor current limit (pins 2,3 of the
Jumper J2).
Connect pin 4 of the SP6650 to GND for 0.35
A peak Inductor current limit (pins 1,2 of the
Jumper J2).
3) V
Programming
To control the output voltage externally con-
nect the appropriate resistors (Table 1)
From pin 6 SP6650 FB
to V
OUT
and to the
GND.
Tie Pin 6 FB
to the 100k resistor or to the
GND and controller will use the internal
network for a preset output Voltage of 3.3V.
For V
different from shown in the Table
1, use equation:
RF =
(
V
OUT
– 1
)
R1
1.25
(For V
OUT
> 3.3V, RF = 50k recommended)
