The ADuM7223 is a 4A isolated, half-bridge gate driver that employ Analog Devices, Inc.?s iCoupler? technology to provide independent and isolated high-side and low-side outputs. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as the combination of pulse transformers and non-isolated gate drivers. By integrating the isolator and driver in a single package, propagation delay is a maximum of only 60 ns and the propagation skew from channel to channel is a maximum of only 7ns.The ADuM7223 provides two independent isolation channels.The ADuM7223 operates with an input supply ranging from 3.0 V to 5.5 V, providing compatibility with lower voltage systems. The outputs operate in a wide range from 4.5V to 18V with three output voltage versions available. The 5 ? 5 mm, LGA package provides 565 V operating voltage from input to output and 700 V from output to output.In comparison to gate drivers employing high voltage level translation methodologies, these gate drivers offer the benefit of true, galvanic isolation between the input and each output. As a result, these gate drivers provide reliable control over the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.APPLICATIONS Switching power supplies Isolated IGBT/MOSFET gate drives Industrial inverters

The ADuM7640?/?ADuM7641?/?ADuM7642?/ ADuM7643 are 6-channel digital isolators based on the Analog Devices, Inc., iCoupler? technology. These 1 kV digital isolation devices are packaged in a small 20-lead QSOP. They offer space savings and a lower price than 2.5 kV or 5 kV isolation solutions when only functional isolation is needed.This family, like many Analog Devices isolators, offers very lowpower consumption, using one-tenth to one-sixth the power of other digital isolators, with the supply voltage on either sideranging from 3.0 V to 5.5 V. Despite their low power consumption,the ADuM7640 / ADuM7641 / ADuM7642 / ADuM7643 provide low pulse width distortion (< 6 ns for C grade) and a channel-by-channel glitch filter to protect the device against extraneous noise disturbances. Four channel direction combinations areavailable with a maximum data rate of 1 Mbps or 25 Mbps. Allproducts have a default output high logic state in the absence of input power.APPLICATIONS General-purpose, multichannel isolation SPI interface/data converter isolation RS-232/RS-422/RS-485 transceivers Industrial field bus isolation

The LTC1625 is a synchronous step-down switching regulator controller that drives external N-Channel power MOSFETs using few external components. Current mode control with MOSFET VDS sensing eliminates the need for a sense resistor and improves efficiency. The frequency of a nominal 150kHz internal oscillator can be synchronized to an external clock over a 1.5:1 frequency range.Burst Mode? operation at low load currents reduces switching losses and low dropout operation extends operating time in battery-powered systems. A forced continuous mode control pin can assist secondary winding regulation by disabling Burst Mode operation when the main output is lightly loaded.Fault protection is provided by foldback current limiting and an output overvoltage comparator. An external capacitor attached to the RUN/SS pin provides soft start capability for supply sequencing. A wide supply range allows operation from 3.7V (3.9V for LTC1625I) to 36V at the input and 1.19V to VIN at the output.Applications Notebook and Palmtop Computers, PDAs Cellular Telephones and Wireless Modems Battery Chargers Distributed Power

The LT8310 is a simple-to-use resonant reset forward converter controller that drives the gate of a low side N-channel MOSFET from an internally regulated 10V supply. The LT8310 features duty mode control that generates a stable, regulated, isolated output using a single power transformer. With the addition of output voltage feedback, via opto-coupler (isolated) or directly wired (nonisolated), current mode regulation is activated, improving output accuracy and load response. The flexibility to choose transformer turns ratio makes high step-down or step-up ratios possible without operating at duty cycle extremes.The user can program the switching frequency from 100kHz to 500kHz to optimize efficiency, performance or external component size. A synchronous output is available for controlling secondary side synchronous rectification to improve efficiency. User programmable protection features include monitors on input voltage (UVLO and OVLO) and switch current (overcurrent limit).
