C Output Voltage Programming
The AAT1142 output voltage is programmed
through the I
2
C interface according to Table 1. The
data register encoded on the SCL and SDA lines
determines the output voltage set-point after initial
start-up. Upon power-up and prior to I
2
C program-
ming, the default output voltage is set to 1.8V.
