The LT3468/LT3468-1/LT3468-2 are highly integrated ICs designed to charge photoflash capacitors in digital and film cameras. A patented control technique* allows for the use of extremely small transformers. Each device contains an on-chip high voltage NPN power switch. Output voltage detection* is completely contained within the device, eliminating the need for any discrete zener diodes or resistors. The output voltage can be adjusted by simply changing the turns ratio of the transformer. The LT3468 has a primary current limit of 1.4A, the LT3468-2 has a 1A limit, and the LT3468-1 has a 0.7A limit. These different current limit levels result in well controlled input currents of 500mA for the LT3468, 375mA for the LT3468-2 and 225mA for the LT3468-1. Aside from the differing current limit, the three devices are otherwise equivalent.The CHARGE pin gives full control of the part to the user. Driving CHARGE low puts the part in shutdown. The DONE pin indicates when the part has completed charging. The LT3468 series of parts are available in tiny low profile (1mm) SOT-23 packages.Applications Digital / Film Camera Flash PDA / Cell Phone Flash Emergency Strobe

Demonstration Circuit 725 is a 7A high efficiency, phase-lockable constant frequency buck converter, incorporating the LTC3415 polyphase monolithic synchronous regulator. The DC725 has an input voltage range of 2.375V to 5.5V and an output voltage range from 0.6V to 5V. The output voltage can be set to 1.2V, 1.5V or 1.8V using the appropriate jumper connection, or it can be set to an adjustable value down to 0.6V, the reference voltage of the LTC3415. The DC725 can deliver high power for a monolithic part (up to 7A of output current) due to the high current power switches (28 mΩ of onstate resistance) of the LTC3415. The LTC3415 can also do polyphase operation, which allows multiple DC725s to be used in parallel for higher current power supplies. Since the parallel LTC3415s can operate out-of-phase, the amount of input and output capacitance required will be minimal.

The ADF4401A is a fully integrated, system in package (SiP) translation loop (also known as an offset loop) module that includes a voltage controlled oscillator (VCO) and calibration phase-locked loop (PLL) circuit. Designed for highly jitter sensitive applications, this solution reduces board space and complexity compared to traditional discrete translation loop solutions designed on a printed circuit board (PCB). The time to market is significantly reduced by taking advantage of this highly integrated solution with in package circuitry and enhanced isolation that attenuates spurious components. The ADF4401A provides a frequency synthesis solution for engineers designing highly competitive systems. The ADF4401A requires an external phase detector or phase frequency detector (PFD) and an external local oscillator (LO) to form a frequency synthesis solution. The ADF4401A implements an integrated downconversion mixing stage in the feedback loop that sets the loop gain to 1 and minimizes the in band phase noise. By combining the frequency downconversion stage and low noise, integrated, wideband, VCO technology from Analog Devices, Inc., the ADF4401A offers a wideband jitter performance of 9 fs rms at 8 GHz output. The output jitter performance is largely dependent on the performance of the external offset LO. The ADF4401A module uses an internal PFD and VCO calibration circuitry to select the appropriate VCO band. The user can disable the calibration circuitry and close the loop using the external PFD. All on-chip registers are controlled via a serial port interface (SPI). APPLICATIONSInstrumentation and measurement Automated test equipment Aerospace and defense

The ADGS1414D contains eight independent SPST switches. A serial peripheral interface (SPI) controls the switches. The SPI has robust error detection features, such as cyclic redundancy check (CRC) error detection, invalid read and write address detection, and SCLK count error detection. It is possible to daisy-chain multiple ADGS1414D devices together. Daisy-chain mode enables the configuration of multiple devices with a minimal amount of digital lines. The route of digital signals and supplies through the ADGS1414D allows for a further increase in channel density. Integrated passive components eliminate the need for external passive components. FUNCTIONAL BLOCK DIAGRAM Figure 1. The ADGS1414D is suited to high density switching applications, such as large switching matrices and fanout applications. Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. Multifunction pin names may be referenced by their relevant function only.Applications?
