Technical Reference Notes
AIF12W300 DC-DC Series
Basic Operation and Features (continued)
Break Regulation
AIF12W300–Series modules are designed to deliver full
rate output current at up to 0.5V above V_{O nom} at the
minimum specified input voltage.
I²C Digital Control (DCS, I²C CLK, I²C DATA)
The module shall be capable to be controlled by I²C
interface, which is SMBus compatible, via I²C CLK and
I²C DATA pins. These two pins share the same pin
location of CLIM ADJ and V ADJ pins respectively.
Digital control is selected when Digital Control Select
(DCS) pin voltage is between 2V to 4V. When digital
control is selected, analog adjust pin function is disabled.
DCS signal shall only be applied when the module is
powered off or disabled. An external 10k pull-up resistor is
necessary for each I²C CLK, and I²C DATA pin, for
100kHz I²C bus frequency.
