The ADN4620/ADN4621 are dual-channel, signal isolated, low voltage differential signaling (LVDS) buffers that operate at up to 2.5 Gbps with very low jitter. The devices integrate Analog Devices, Inc., iCoupler? technology, enhanced for high speed operation to provide drop-in galvanic isolation of LVDS signal chains. AC coupling and/or level shifting to the LVDS receivers and from the LVDS drivers allows isolation of other high speed signals, such as current mode logic (CML).The ADN4620/ADN4621 include a refresh mechanism to monitor the input and output states and ensure that they remain the same in the absence of data transitions (for example, at power-on). For lower power consumption and high speed operation with low jitter, the isolator circuits rely on 1.8 V supplies, while 3.3 V supplies are used for LVDS receivers to support the full common-mode range with an input voltage range (input common mode plus differential input voltage) of 0 V to 2.4 V per Table 2 in the data sheet.The devices are fully specified over a wide industrial temperature range and are available in a compact SSOP package with 5.3 mm creepage (for reinforced insulation at ac mains voltages).APPLICATIONS Analog front-end isolation Data plane isolation Isolated high speed clock and data links Multigigabit serialization/deserialization (SERDES) PCB-to-PCB optical replacement (for example, short reach fiber)Protected by U.S. Patents 7,075,329; 9,941,565; and 10,205,442.

The LTC7132 is a dual output PolyPhase DC/DC synchronous step-down monolithic regulator with an I2C-based PMBus compliant serial interface. The regulator employs a constant-frequency current mode architecture, together with a unique scheme to provide excellent performance in sub-milliohm DCR applications. The LTC7132 is supported by the LTpowerPlay? software development tool with graphical user interface (GUI).Programmable loop compensation allows the regulator to be compensated digitally. The switching frequency, channel phasing and device address can be programmed both by the digital interface as well as the external configuration resistors. Additionally, parameters can be set via the digital interface and stored in EEPROM. Both outputs have independent power good indicators and FAULT function.The LTC7132 can be configured to operate in discontinuous (pulse-skipping) mode or forced continuous conduction mode. Each channel can deliver up to 25A of loadcurrent; the total current capability will depend on the APPLICATIONS total power dissipations on both channels.POWER CONVERSION Wide VIN Range: 4.5V to 20V VOUT Range: 0.5V to 3.5V (with Ultralow DCR Setting); 0.5V to 5.5V (Typical DCR Setting) Accurate PolyPhase?

Demonstration circuit 1510A is a high output voltage, high efficiency synchronous poly-phase buck converter featuring the LTC3858EUH. The demo circuit is available in two versions. The input voltage of both versions is 16V to 26V. DC1510A-A is configured using 2 LTC3858's with 4 phase interleaving operation which provides a 12V/50A output, while the DC1510A-B is configured with 1 LTC3858 with 2 phase inter-leaving operation which provides a 12V/25A output.

The LT8650S is a dual step-down regulator that delivers up to 4A of continuous current from both channels and supports loads up to 6A from each channel. The LT8650S features the second generation Silent Switcher architecture to minimize EMI emissions while delivering high efficiency at high switching frequencies. This includes integration of bypass capacitors to optimize high frequency current loops and make it easy to achieve advertised EMI performance by eliminating layout sensitivity.The fast, clean, low-overshoot switching edges enable high efficiency operation even at high switching frequencies, leading to a small overall solution size. Peak current mode control with a 40ns minimum on-time allows high step down ratios at high switching frequencies.Burst Mode operation features a 6.2?A quiescent current resulting in high efficiency at low output currents, forced continuous mode allows fixed switching frequency operation over the entire output load range, and spread spectrum operation can further reduce EMI emissions. External VC pins allow optimal loop compensation for fast transient response. The VC pins can also be used for current sharing and the CLKOUT pin enables synchronizing two LT8650S chips to generate a 4-phase, 16A supply.APPLICATIONS General Purpose Step-Down Automotive and Industrial Supplies

The LT1317/LT1317B are micropower, fixed frequency step-up DC/DC converters that operate over a wide input voltage range of 1.5V to 12V. The LT1317 features automatic shifting to power saving Burst Mode? operation at light loads. High efficiency is maintained over a broad 300?A to 200mA load range. Peak switch current during Burst Mode operation is kept below 250mA for most operating conditions which results in low output ripple voltage, even at high input voltages. The LT1317B does not shift into Burst Mode operation at light loads, eliminating low frequency output ripple at the expense of light load efficiency.The LT1317/LT1317B contain an internal low-battery detector with a 200mV reference that stays alive when the device goes into shutdown.No-load quiescent current of the LT1317 is 100?A and shuts down to 30?A. The internal NPN power switch handles a 500mA current with a voltage drop of just 300mV.The LT1317/LT1317B are available in MS8 and SO-8 packages.Applications Cellular Telephones Cordless Telephones Pagers GPS Receivers Battery Backup Portable Electronic Equipment Glucose Meters Diagnostic Medical Instrumentation

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). The LT8310 soft-start feature helps protect the transformer from flux saturation.Applications Industrial, Automotive and Military Systems 48V Telecommunication Isolated Power Supplies Isolated and Nonisolated DC/DC Converters
