The ADuM4136 is a single-channel gate driver specifically optimized for driving insulated gate bipolar transistors (IGBTs). Analog Devices, Inc., iCoupler? technology provides isolation between the input signal and the output gate drive.Operation with unipolar or bipolar secondary supplies is possible, allowing negative gate drive if needed.The Analog Devices chip scale transformers also provide isolated communication of control information between the high voltage and low voltage domains of the chip. Information on the status of the chip can be read back from dedicated outputs. Control of resetting the device after a fault on the secondary side is performed on the primary side of the device.Integrated onto the ADuM4136 is a desaturation detection circuit that provides protection against high voltage short-circuit IGBT operation. The desaturation protection contains noise reducing features such as a 312 ns (typical) masking time after a switching event to mask voltage spikes due to initial turn-on. An internal 537 ?A (typical) current source allows low device count, and the internal blanking switch allows the addition of an external current source if more noise immunity is needed.The secondary UVLO is set to 12 V with common IGBT threshold levels taken into consideration.Applications MOSFET/IGBT gate drivers Photovoltaic (PV) inverters Motor drives Power supplies

The ADuM4221/ADuM4221-1/ADuM4221-2 are 4 A isolated, half bridge gate drivers that employ the Analog Devices, Inc., iCoupler? technology to provide independent and isolated high-side and low-side outputs. The ADuM4221/ADuM4221-1/ADuM4221-2 provide 5700 V rms isolation in an increased creepage wide body, 16-lead SOIC_IC. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to the alternatives, such as the combination of pulse transformers and gate drivers.The isolators operate with a logic input voltage ranging from 2.5 V to 6.5 V, providing compatibility with lower voltage systems. In comparison to gate drivers employing high voltage level translation methodologies, the ADuM4221/ADuM4221-1/ADuM4221-2 offer the benefit of true, galvanic isolation between the input and each output.The ADuM4221/ADuM4221-1/ADuM4221-2 each have built in overlap protection and allow dead time adjustment. A single resistor between the dead time pin (DT) and the GND1 pin sets the dead time on the secondary side between the high-side and the low-side outputs.An internal thermal shutdown (TSD) sets outputs low if the internal temperature on the ADuM4221/ADuM4221-1/ADuM4221-2 exceeds the TSD temperature. As a result, the ADuM4221/ADuM4221-1/ADuM4221-2 provide reliable control over the switching characteristics of the insulated gate bipolar transistor (IGBT)/metal-oxide semiconductor field effect transistor (MOSFET) configurations over a wide range of positive or negative switching voltages.Applications Switching power supplies Isolated IGBT/MOSFET gate drives Industrial inverters Gallium nitride (GaN)/silicon carbide (SiC) compatible1 Protected by U.S. Patents 5,952,849; 6,873,065; 7,075,239.

The ADuM5020 is an isoPower?, 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 below CISPR22 Class B limits at full load on a 2-layer printed circuit board (PCB) with ferrites. The ADuM5020 eliminates the need to design and build an isolated dc-to-dc converter in 500 mW applications. The iCoupler chip scale transformer technology is used for the magnetic components of the dc-to-dc converter. The result is a small form factor, isolated solution.The ADuM5020 isolated dc-to-dc converter is available in a wide-body 16-lead SOIC package.Applications RS-485/RS-422/CAN transceiver power Power supply startup bias and gate drives Isolated sensor interfaces Industrial PLCs

Evaluation circuit EVAL-LT8333-AZ features the LT8333 in a SEPIC configuration. It operates with a switching frequency of 2MHz and is designed to convert a 3V to 26V source to 12V output. The converter can output up to 1.25A depending on the input voltage (see Figure 3 in the demo manual, maximum output current vs VIN curve). This evaluation circuit features Spread Spectrum Frequency Modulation (SSFM) and EMI filters to provide optimum EMI performance. This PCB layout is optimized for good EMI performance and small solution size. The evaluation board contains a selectable jumper, JP1, to aid in the selection of the desired SYNC pin mode of operation. At light load, either pulse-skipping (PULSE SKIP) or low-ripple Burst Mode® operation (BURST) can be selected to improve the efficiency. The LT8333 boost/SEPIC/inverting converter IC operates over an input range of 2.8V to 40V, suitable for automotive, telecom, and industrial applications. The converter provides adjustable and synchronizable operation from 300kHz to 2MHz with SSFM option. The LT8333 packs other popular features such as soft-start, bias pin, input undervoltage lockout. The IC can exhibit a low quiescent current down to 9μA in BURST mode and 1μA in shutdown, which makes it ideal for battery-operated systems. The LT8333 is assembled in a thermally enhanced 10-lead 3mm × 3mm DFN package. The data sheet gives a complete description of the device, operation, and application information. The data sheet must be read in conjunction with the demo manual for EVAL-LT8333-AZ.
