ADUM6132: Isolated Half-Bridge Driver with Integrated Isolated High-Side Supply
Product Description
The ADuM61321 is an isolated half-bridge gate driver that employs the Analog Devices, Inc., iCoupler® technology to provide an isolated high-side driver with an integrated 275 mW high-side supply. This supply, provided by an internal isolated dc-to-dc converter, powers not only the ADuM6132 high-side output but also any external buffer circuitry that is commonly used with the ADuM6132. This functionality eliminates the cost, space, and performance issues associated with external supply configurations such as a bootstrap circuit.
The architecture of the ADuM6132 isolates the high-side channel and the high-side power from the control and low- side interface circuitry. Care has been taken to ensure close matching between the high-side and low-side driver timing characteristics to reduce the need for a dead time margin.
In comparison to gate drivers that employ high voltage level translation methodologies, the ADuM6132 offers the benefit of true, galvanic isolation. The differential voltage between high-side and low-side channels can be as high as 800 V with good insulation lifetime (see Table 12).
isoPower® uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards. Refer to the AN-0971 Application Note for details on board layout considerations.
