Instructions
The numbers in the instructions below correspond
to the numbers in Figure 1. By following the number
sequence below, the device can be turned on by
step 5.
1)
ENABLE
– The jumper on the left two pins
of JP9 enables the device through the
resistor R10. The jumper on the right two
pins of JP9 disables the device.
2)
Output Voltage Settings (JP1-JP8)
- The
jumper may be switched to change the
output voltage. From left to right R1 to R8
(1.5V-15V). The EY1603TI-ADJ output
voltage is programmed using an external
resistor divider.
