Fujitsu 5V-Only Flash memory cards are electrically erasable and programmable memory cards capable of storing and retrieving large amounts of data. They are housed in a credit-card sized 68-pin package and offer additional EEPROM memory that is used to store attribute data. The attribute memory is a Flash memory card option.

This data sheet introduces the features of the F2MC-16LX MB90520A/520B series 16-bit proprietary microcontrollers

The MAX8550/MAX8551 integrate a synchronous-buck PWM controller to generate VDDQ, a sourcing and sinking LDO linear regulator to generate VTT, and a 10mA reference output buffer to generate VTTR. The buck controller drives two external N-channel MOSFETs to generate output voltages down to 0.7V from a 2V to 28V input with output currents up to 15A. The LDO can sink or source up to 1.5A continuous and 3A peak current. Both the LDO output and the 10mA reference buffer output can be made to track the REFIN voltage. These features make the MAX8550/MAX8551 ideally suited for DDR memory applications in desktops, notebooks, and graphic cards. The PWM controller in the MAX8550/MAX8551 utilizes Maxim’s proprietary Quick-PWM™ architecture with programmable switching frequencies of up to 600kHz. This control scheme handles wide input/output voltage ratios with ease and provides 100ns response to load transients while maintaining high efficiency and a relatively constant switching frequency. The MAX8550 offers fully programmable UVP/OVP and skip-mode options ideal in portable applications. Skip mode allows for improved efficiency at lighter loads. The MAX8551, which is targeted towards desktop and graphic-card applications, does not offer the pulse-skip feature. The VTT and VTTR outputs track to within 1% of VREFIN / 2. The high bandwidth of this LDO regulator allows excellent transient response without the need for bulk capacitors, thus reducing cost and board space.

MAX786 is a system-engineered power-supply controller for notebook computers or similar battery-powered equipment. It provides two high-performance step-down (buck) pulse-width modulators (PWMs) for +3.3V and +5V. Other features include dual, low-dropout, micropower linear regulators for CMOS/RTC back-up, and two precision low-battery-detection comparators. High efficiency (95% at 2A; greater than 80% at loads from 5mA to 3A) is achieved through synchronous recti- fication and PWM operation at heavy loads, and Idle ModeTM operation at light loads. The MAX786 uses physically small components, thanks to high operating frequencies (300kHz/200kHz) and a new current-mode PWM architecture that allows for output filter capacitors as small as 30µF per ampere of load. Line- and load-transient responses are terrific, with a high 60kHz unity-gain crossover frequency allowing output transients to be corrected within four or five clock cycles. Low sys- tem cost is achieved through a high level of integration and the use of low-cost, external N-channel MOSFETs. Other features include low-noise, fixed-frequency PWM operation at moderate to heavy loads, and a synchro- nizable oscillator for noise-sensitive applications such as electromagnetic pen-based systems and communi- cating computers. The MAX786 is a monolithic, BiCMOS IC available in fine-pitch, surface-mount SSOP packages.

The MAX774/MAX775/MAX776 inverting switching regulators deliver high efficiency over three decades of load current. A unique current-limited, pulse-frequency-modulated (PFM) control scheme provides the benefits of pulse-width modulation (high efficiency with heavy loads), while using less than 100µA of sup- ply current (vs. 2mA to 10mA for PWM converters). The result is high efficiency over a wide range of loads. These ICs also use tiny external components; their high switching frequency (up to 300kHz) allows for less than 5mm diameter surface-mount magnetics. The MAX774/MAX775/MAX776 accept input voltages from 3V to 16.5V, and have preset output voltages of -5V, -12V, and -15V, respectively. Or, the output voltage can be user-adjusted with two resistors. Maximum VIN - VOUT differential voltage is limited only by the break- down voltage of the chosen external switch transistor. These inverters use external P-channel MOSFET switch- es, allowing them to power loads up to 5W. If less power is required, use the MAX764/MAX765/MAX766 inverting switching regulators with on-board MOSFETs.

This document describes the analysis of frying fat using Agilent PLgel columns and gel permeation chromatography. By separating compounds of different molecular sizes, the content of high molecular weight substances in fats can be determined, thereby evaluating the quality and properties of the fats.

This document discusses the assessment of the purity of frying fats using Agilent PLgel and gel permeation chromatography. The analysis involves the separation of oligomeric glycerides based on molecular size in solution, allowing for the separation of the major component (monoglyceride) from the minor components (diglyceride, triglyceride) of frying fat. Quantitative analysis can then be performed to obtain information about the purity of the monoglyceride.

This application note describes the benefits of the Agilent 2100 bioanalyzer in real-time quantitative PCR (QPCR) experiments. The results show that the Agilent 2100 bioanalyzer is an indispensable tool to ensure experimental success by verifying RNA template quality prior to QPCR experiments and to improve the assay design and validation process by monitoring size and purity of the QPCR amplicons.

This application note describes the applications and experimental considerations for FastMAS and UltraFastMAS techniques. FastMAS and UltraFastMAS techniques enable experiments with rotation speeds of 40 to 65 kHz, which reduces linewidths and suppresses spin diffusion caused by proton-proton dipolar interactions. These techniques enable experiments such as direct proton observe or solid-state HETCOR to collect spectra comparable to those that formerly required both spinning and experimentally difficult multiple-pulse homonuclear decoupling sequences. Another advantage of FastMAS and UltraFastMAS techniques is that they suppress spin diffusion between protons, allowing experiments to be conveniently performed on individual protons in single or multiple dimensional experiments.

This document describes the enhanced analysis of semi-volatile compounds using sub-ambient ELSD and HPLC. Evaporative light scattering detection (ELSD) is a powerful tool that can detect any sample that is less volatile than the mobile phase in HPLC applications, regardless of the optical properties of the compounds. ELSD offers distinct advantages over conventional UV or DAD detection, especially for gradient separations. In order to maximize the detection of non-UV absorbing semi-volatile analytes, ELSD detectors need to operate at lower temperatures. Most ELSDs today can evaporate highly aqueous eluents at ambient temperature, but for low molecular weight, low boiling point compounds, ambient temperature is still too high and sensitivity is poor. Sub-ambient ELSD is required to improve the detection of these compounds. The Agilent 385-ELSD is specifically designed to operate under these demanding conditions. It features a Peltier cooled evaporation tube that provides sub-ambient ELS detection down to 10 °C. Dry nitrogen gas is added during the evaporation step to facilitate solvent removal at sub-ambient temperatures.
