The AMC3302 offers a fully integrated isolated DC/DC converter that includes following components illustrated in the Section 7.2:

• Low-dropout regulator (LDO) on the low-side side to stabilize the supply voltage VDD that drives the low-side of the converter. This circuit does not output a constant voltage and is not intended for driving any external load.
• Low-side full-bridge inverter and drivers.
• Laminate-based, air-core transformer for high immunity to magnetic fields.
• High-side full-bridge rectifier.
• High-side LDO to stabilize the output voltage of the DC/DC converter for high analog performance of the signal path.

The DC/DC converter uses a spread-spectrum clock generation technique to reduce the spectral density of the electromagnetic radiation. The resonator frequency is synchronized to the operation of the ΔΣ modulator to minimize the interference with data transmission and support the high analog performance of the device.

The architecture of the DC/DC converter is optimized to drive the high-side circuitry of the AMC3302 and can source up to I_H of additional DC current for an optional auxiliary circuit such as an active filter, preamplifier, or comparator. I_H is specified in the Section 6.9 table as a DC, non-switching current.
