@ reference manual 6.5 Internal Power Supplies

The 3.3V (Fig. 27) and 1.8V Fig. 28 analog power supplies are implemented around an ADP2138 Fixed Output Voltage, 800mA, 3MHz, Step-Down DC-to-DC converter.

3.3Vと1.8Vがあるとのこと。

The -3.3V analog power supply (Fig. 29) is implemented with the ADP2301 Step-Down regulator in an inverting Buck-Boost configuration.

-3.3Vもあるようだ。

The 5.5V and -5.5V supplies Fig. 30 are created with a Sepic-Cuk topology, built around a single ADP1612 Step-Up DC-to DC converter.

加えて 5.5V / -5.5V。

これらの電圧出力がAD2内部でどのように使われ、ユーザ側でどのように提供されているかは未学習。
