SW10
N/A
To start the loading at power up, set SW6 pin 3 to
ON
(pull to GND).
To control the start manually, set SW6 pin 1 to
ON
(pull to VDD) and push
the SW10 button for the high-to-low transition to start the loading. When
loading is complete, the LED – D1 will turn off.

Quick Start Guide
1. Connect J19: V
IN
= 3.3 V or V
DD
= 2.5 V and GND.
•
For V
IN
= 3.3 V: Set SW7 pin1 (VDD_SEL) to the
ON
position (enable internal LDO regulator) and
float V
DD
at J19.
•
For V
IN
= 2.5 V: Set SW7 pin1 (VDD_SEL) to the OFF positions (disable internal LDO regulator)
and float V
IN
at J19.
2. Set Jumper J20 for V
IH
connection to V
IN
or V
DD
.
•
For 3.3 V mode: V
IH
tied to V
IN
(see
)
•
For 2.5 V mode: V
IH
tied to V
DD
(see
)
3. Set the control switches for normal operation:
