The toggling of the slew rate is controlled by the primary side. Slew rate control can allow for electromagnetic interference (EMI) mitigation and voltage overshoot control.An internal thermal shutdown sets outputs low if internal temperatures on the ADuM4122 exceed the thermal shutdown temperature.As a result, the ADuM4122 provides reliable control over the switching characteristics of insulated gate bipolar transistor (IGBT) and metal-oxide semiconductor field effect transistor (MOSFET) configurations over a wide range of switching voltages, allowing for simple slew rate control.Applications Switching power supplies Isolated IGBT and MOSFET gate drivers Industrial inverters

The ADuM4165/ADuM41661 are USB 2.0 port isolators, utilizing Analog Devices, Inc., iCoupler? technology to dynamically support all USB 2.0 data rates; low (1.5 Mbps), full (12 Mbps), or high (480 Mbps), as required. The devices support host isolation with automatic speed negotiation as well as peripheral isolation.High speed data is retimed for jitter reduction, requiring an external clock signal or crystal input. The ADuM4165 supports the clock or crystal input on the upstream side, and the ADuM4166 supports the clock or crystal input on the downstream side, offering two options to best suit the system design.The low power standby mode for downstream (Side 2) supports applications with limited available power, such as battery-operated peripherals. The upstream (Side 1) standby current meets USB 2.0 requirements for suspended operation.The isolators are specified over an extended industrial temperature range of ?55?C to +125?C and are available in a 20-lead, wide-body, increased creepage SOIC_IC with 8.3 mm creepage and clearance.APPLICATIONSUSB peripheral, USB host, and USB hub isolationElectronic test and measurement equipmentMedical devices and integrated PCsIndustrial PCs and isolated USB ports for debug or upgradeUSB isolator modules and USB cable isolators1 Protected by U.S. Patents 7,075,329; 8,432,182; 8,525,547; and 8,564,327.

The LTC3882 is a dual, PolyPhase DC/DC synchronous step-down switching regulator controller with PMBus compliant serial interface. It uses a constant frequency, leading-edge modulation, voltage mode architecture for excellent transient response and output regulation. Each PWM channel can produce output voltages from 0.5V to 5.25V using a wide range of 3.3V compatible power stages, including power blocks, DrMOS or discrete FET drivers. Up to four LTC3882s can operate in parallel for 2-, 3-, 4-, 6- or 8-phase operation.LTC3882 system configuration and monitoring is supported by the LTpowerPlay? software tool. The device?s serial interface can be used to read back input voltage, output voltage and current, temperature and fault status. A wide range of operating parameters can be set via the digital interface or stored in internal EEPROM for use at power up. Switching frequency and phase, output voltage and device address can also be programmed using external configuration resistors.
