ADUM5212Dual-Channel Isolators with Integrated DC-to-DC Converter (0/2 Channel Directionality) | Isolators | 6 | Active | TheADuM5210/ADuM5211/ ADuM5212 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 in the data sheet.The ADuM5210 / ADuM5211 / ADuM5212 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.

ADUM5230Isolated Half-Bridge Driver with Integrated High-Side Supply | Isolators | 4 | Active | The ADuM5230 is an isolated half-bridge gate driver that employs Analog Devices, Inc.,iCoupler®technology to provide independent and isolated high-side and low-side outputs. Combining CMOS and microtransformer technologies, this isolation component contains an integrated dc-to-dc converter providing an isolated high-side supply. This eliminates the cost, space, and performance difficulties associated with external supply configurations such as bootstrap circuitry. This highside isolated supply powers not only the ADuM5230 high-side output but also any external buffer circuitry used with the ADuM5230.In comparison to gate drivers employing high voltage level translation methodologies, the ADuM5230 offers the benefit of true, galvanic isolation between the input and each output. Each output can operate up to ±700 VPrelative 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 700 VP.ApplicationsMOSFET/IGBT gate drivesAutomotiveMotor drivesPower supplies |

ADUM5241Dual-Channel Isolators withisoPower®Integrated DC/DC Converter, 50mW (1/1 channel directionality) | Digital Isolators | 2 | Active | The ADuM524x are dual-channel digital isolators withisoPower integrated, isolated power. Based on the Analog Devices, Inc.iCoupler®technology, a chip-scale DC/DC converter provides up to 50 mW of regulated, isolated power at 5 V, which eliminates the need for a separate isolated DC/DC converter in low power isolated designs. The Analog Devices chip-scale transformeriCoupler technology is used both for the isolation of the logic signals as well as for the DC/DC converter. The result is a small form factor, total isolation solution.The ADuM524x isolators provide two independent isolation channels in a variety of channel configurations, operating from a 5 V input supply. ADuM524x units may be used in combination with otheriCoupler products to achieve greater channel counts. |

ADUM5401Quad-Channel, 2.5 kV Isolators with Integrated DC-to-DC Converter (3/1 channel directionality) | Isolators | 8 | Active | The ADuM5401 /ADuM5402/ADuM5403/ADuM5404are quad-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 up to 500 mW of regulated, isolated power at either 5.0 V or 3.3 V from a 5.0 V input supply, or at 3.3 V from a 3.3 V supply at the power levels shown in Table 1. These devices eliminate the need for a separate, isolated dc-to-dc converter in low power, isolated designs. TheiCoupler chip scale transformer technology is used to isolate the logic signals and for the power and feedback paths in the dc-to-dc converter. The result is a small form factor, total isolation solution.The ADuM5401 / ADuM5402 / ADuM5403 / ADuM5404 isolators provide four independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide for more information).isoPower uses high frequency switching elements to transfer power through its transformer.
