ADUM6212Dual-Channel Isolators with Integrated DC-to-DC Converter (0/2 Channel Directionality) | Digital Isolators | 6 | Active | TheADuM6210/ADuM6211/ ADuM6212 are dual-channel digital isolators withisoPower®, an integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc.,iCoupler®technology, the dc-to-dc converter provides regulated, isolated power that is adjustable between 3.135 V and 5.25 V. Input supply voltages can range from slightly below the required output to significantly higher. Popular voltage combinations and their associated power levels are shown in Table 2.The ADuM6210 / ADuM6211 / ADuM6212 eliminate the need for a separate, isolated dc-to-dc converter in low power, isolated designs. TheiCoupler chip-scale transformer technology is used for isolated logic signals and for the magnetic components of the dc-to-dc converter. The result is a small form factor, total isolation solution.isoPower uses high frequency switching elements to transfer power through its transformer. Take special care during printed circuit board (PCB) layout to meet emissions standards.

ADUM7234Isolated Precision Half-Bridge Driver, 4 A Output | Isolators - Gate Drivers | 2 | Active | The ADuM7234 is an isolated, half-bridge gate driver that employs the Analog Devices, Inc.,iCoupler®technology to provide independent and isolated high-side and low-side outputs. Combining high speed CMOS and monolithic transformer technology, this isolation component provides outstanding performance characteristics superior to optocoupler-based solutions. By avoiding the use of LEDs and photodiodes, thisiCoupler gate drive device is able to provide precision timing characteristics not possible with optocouplers. Furthermore, the reliability and performance stability problems associated with optocoupler LEDs are avoided.In comparison to gate drivers employing high voltage level translation methodologies, the ADuM7234 offers the benefit of true, galvanic isolation between the input and each output. Each output may be operated up to ±350 V peak relative to the input, thereby supporting low-side switching to negative voltages. The differential voltage between the high side and low side may be as high as 350 V peak.As a result, the ADuM7234 provides reliable control over the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.ApplicationsIsolated IGBT/MOSFET gate drivesPlasma displaysIndustrial invertersSwitching power supplies |
