Operational Guidelines
1. Connect a dc input voltage, within the 6.0 V to 36
V range, between VBAT and GND
.
2. Connect a load (< 150 mA) between VOUT1 and
GND
3. Connect a dc enable voltage, within the 2.0 V to
36 V range, between EN and GND. This will
enable the internal LDO for low Iq mode. You
may use jumper J1 to connect EN directly to
VBAT.
a. The VOUT1 signal should be 5.0 V.
b. The VOUT2 signal should be disabled
(regardless of EN2 state) and read 0 V.
c. The VOUT3 signal should be disabled
(regardless of EN3 state) and read 0 V.
4. Connect a dc enable voltage, within the 2.0 V to
36 V range, between STBYB and GND. This will
exit low Iq mode and power up switcher 1. You
may use jumper J2 to connect STBYB directly to
VBAT.
The VOUT1 signal should still be 5.0 V. You
may now add a higher load to VOUT1.
5. Connect a dc enable voltage, within the 2.0 V to
6 V range, between EN2 and GND. This will
power up switcher 2
.
You may use jumper J4 to
connect EN2 directly to VOUT1.
The VOUT2 signal should be 3.3 V.
6. Connect a dc enable voltage, within the 2.0 V to
6 V range, between EN3 and GND. This will
power up switcher 3
.
You may use jumper J3 to
connect EN3 directly to VOUT1.
The VOUT3 signal should be 1.2 V.
