The LTC3370 is a highly flexible multioutput power supply IC. The device includes four synchronous buck converters, configured to share eight 1A power stages, each of which is powered from independent 2.25V to 5.5V inputs.The DC/DCs are assigned to one of eight power configurations via pin programmable C1-C3 pins. The common buck switching frequency may be programmed with an external resistor, synchronized to an external oscillator, or set to a default internal 2MHz clock.The operating mode for all DC/DCs may be programmed via the PLL/MODE pin for Burst Mode or forced continuous mode operation. A PGOODALL output indicates when all enabled DC/DCs are within a specified percentage of their final output value.To reduce input noise, the buck converters are phased in 90? steps. Precision enable pin thresholds facilitate reliable power-up sequencing. The LTC3370 is available in a 32-lead 5mm ? 5mm QFN package.Applications General Purpose Multichannel Power Supplies:?Automotive, Industrial, Distributed Power Systems

The LT3825 is an isolated switching regulator controller designed for medium power flyback topologies. A typical application is 10W to 60W with input voltage limited only by external power path components. A third transformer winding provides output voltage feedback.The LT3825 is a current mode controller that regulates output voltage based on sensing secondary voltage via a transformer winding during flyback. This allows for tight output regulation without the use of an opto-isolator, improving dynamic response and reliability. Synchronous rectification increases converter efficiency and improves output cross regulation in multiple output converters.The LT3825 operates in forced continuous conduction mode which improves cross regulation in multiple winding applications. Switching frequency is user programmable and can be externally synchronized. The part also has load compensation, undervoltage lockout and soft-start circuity.Applications Isolated Medium Power (10W to 60W) Supplies Isolated Telecom, Medical Converters Instrumentation Power Supplies Isolated Power over Ethernet Supplies

The LTC6405 is unity gain stable and the closed-loop bandwidth extends from DC to 800MHz. The output voltage swing extends from near-ground to 4V, to be compatible with a wide range of ADC converter input requirements. The LTC6405 draws only 18mA, and has a hardware shutdown feature which reduces current consumption to 400?A.The LTC6405 is available in a compact 3mm ? 3mm 16?pin leadless QFN package, as well as an 8-lead MSOP package, and operates over a ?40?C to 85?C temperature range.Applications Differential Input ADC Driver Single-Ended to Differential Conversion Level-Shifting Ground-Referenced Signals Level-Shifting VCC-Referenced Signals High-Linearity Direct Conversion Receivers
