Demonstration circuit 894B-C is a 36V-72Vin, synchronous flyback converter featuring the LT3825. This circuit was designed specifically to attain a high current, low ripple, synchronously rectified flyback to efficiently power 12V loads at up to 5A from a typical telecom input voltage range. This circuit features synchronous rectifier drive outputs, output voltage regulation without the need of an optocoupler, self-starting architecture and input undervoltage lockout.

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 DC9010B Eterna Serial Programmer provides in-circuit access to Eterna based products (such as the LTC5800, LTP5900, LTP5901, or LTP5902) and is used to load SmartMesh networking software. Eterna is the powerful, low power ARM Cortex-M3 System-on-Chip that includes 512kbytes of on board flash memory. Refer to the Eterna Serial Programmer Guide for additional information. The DC9010B consists of an enclosed circuit board with a USB micro-B interface and a 2x5 pin 2mm ribbon cable and is used in conjunction with the Eterna Serial Programmer (ESP) software. An alternative to the DC9010B Eterna Serial Programmer is the DC9006 Eterna Interface Card (when connected with a DC9004 adaptor card). The DC9006/DC9004 is included in SmartMesh IP starter kits and performs many, but not all, of the same functions as the DC9010B. For more details, please visit the DC9006 web page.

The LTC3204-3.3/LTC3204-5/LTC3204B-3.3/LTC3204B-5 are low noise, constant frequency (1.2MHz) switched capacitor voltage doublers. The LTC3204-3.3/ LTC3204B-3.3 can produce a regulated output voltage of 3.3V from a minimum input voltage of 1.8V (2 alkaline cells) whereas the LTC3204-5/LTC3204B-5 can produce 5V from a minimum of 2.7V (Li-Ion battery) input.LTC3204-3.3/LTC3204-5 feature automatic Burst Mode? operation at light loads to maintain low supply current whereas LTC3204B-3.3/LTC3204B-5 feature constant frequency operation at any load. Built-in soft-start circuitry prevents excessive inrush current during start-up. Thermal shutdown and current-limit circuitry allow the parts to survive a continuous short-circuit from VOUT to GND.High switching frequency minimizes overall solution footprint by allowing the use of tiny ceramic capacitors. In shutdown, the load is disconnected from the input and the quiescent current is reduced to

Demonstration circuit 916 is a low noise regulated charge pump featuring the LTC3204B (constant frequency switching) in the 2X2 DFN package. There are two assembly versions, DC916A-A and DC916A-B for the LTC3204B-5 (5V output) and LTC3204B-3.3 (3.3V output) respectively. The DC916A-B produces a regulated 3.3V output from a 1.8V to 4.5V input. The guaranteed output current is 50mA from VIN between 1.9V and 4.5V, and 40mA for VIN less than 1.9V.

The ADP5090 is an integrated boost regulator that converts dc power from PV cells or TEGs. The device charges storage elements such as rechargeable Li-Ion batteries, thin film batteries, super capacitors, and conventional capacitors, and powers up small electronic devices and battery-free systems.The ADP5090 provides efficient conversion of the harvested limited power from a 16 ?W to 200 mW range with sub-?W operation losses. With the internal cold-start circuit, the regulator can start operating at an input voltage as low as 380 mV. After cold startup, the regulator is functional at an input voltage range of 80 mV to 3.3 V.By sensing the input voltage at the VIN pin, the control loop keeps the input voltage ripple in a fixed range to maintain stable dcto-dc boost conversion. The VIN OCV sensing and programmable regulation points of the input voltage allow extraction of the highest possible energy from the PV cell or TEG harvester. A programmable minimum operation threshold (MINOP) enables boost shutdown during a low light condition. In addition, the DIS_SW pin can temporarily shut down the boost regulator and is RF transmission friendly.The charging control function of ADP5090 protects rechargeable energy storage, which is achieved by monitoring the battery voltage with programmable charging termination voltage and shutdown discharging voltage. In addition, a programmable PGOOD flag monitors the SYS voltage.An optional primary cell battery can be connected and managed by an integrated power path management control block that automatically switches the power source from the energy harvester, rechargeable battery, and primary cell battery.The ADP5090 is available in a 16-lead, 3 mm ? 3 mm LFCSP and is rated for a ?40?C to +125?C junction temperature range.APPLICATIONS PV cell energy harvesting TEG energy harvesting Battery regulator powered by solar panel Industrial monitoring Self-powered wireless sensor devices Portable and wearable devices with energy harvesting
