DC817A: Demo Board for the LTC2927 Single Power Supply Tracking Controller.

CC2541 Mini Development Kit

The DC2875A is a demonstration system for the LTC2971 Power System Manager that interfaces to various regulators. The board contains all the circuitry needed to demonstrate a power system that utilizes two 2-channel LTC2971 devices that manage four power supplies. The four power supplies include various switching regulators for the purpose of demonstrating a variety of methods to sense voltage and current. The demo board provides a sophisticated 4-channel digitally programmable power supply system. The LTC2971 is a 2-channel I2C/SMBus/PMBus Power System Manager that features accurate input current and energy measurement and is capable of managing ±60V supplies. The device monitors input current and input voltage, and calculates input power and energy. The DC2875A demonstrates the ability of the LTC2971 to sequence, trim, margin, supervise, monitor, and log faults for four power supplies. The LTC2971 monitors each channel’s output voltage and output current and also monitors each channel’s external temperature sensor and its own internal die temperature. The DC2875A board contains four independent power supply rails. All four rails are based on DC/DC switching regulators. The +36V and +32V channels are managed by an LTC2971 and the ±24V channels are managed by an LTC2971-1. The board is pre-configured with these voltages and may be re-configured with feedback resistors. The LTpowerPlay® graphical user interface (GUI) supports this demonstration system and enables complete control of all the features of the LTC2971. Together, the LTpowerPlay software and DC2875A hardware system create a powerful development environment for designing and testing configuration settings of the LTC2971. LTpowerPlay stores these settings in the LTC2971 internal EEPROM or in a project file. The software displays all of the configuration settings and real time measurements from the Power System Management IC. Telemetry allows easy access and decoding of the fault log created by the LTC2971. The board comes preprogrammed with the EEPROM values appropriate for the four power supply rails on the DC2875A. Just plug and play! Order pre-programmed devices from Analog Devices Express (ADX) using LTpowerPlay.

The LTC7124 is a dual channel, 3.5A per output, high efficiency monolithic step-down regulator capable of operating from input supplies up to 17V. The programmable switching frequency ranges from 500kHz to 4MHz with a ?25% external clock synchronization capability around the programmed frequency. The regulator features ultralow quiescent current for high efficiency over a wide VOUT range.The step-down regulator operates from an input voltage range of 3.1V to 17V and provides an adjustable output range from 0.6V to 99% of VIN while delivering up to 3.5A of output current per channel. A user selectable mode input is provided to allow the user to trade off output ripple for light load efficiency; Burst Mode? operation provides the highest efficiency at light loads, while forced continuous operation provides the lowest output ripple. The LTC7124 includes spread spectrum modulation for low radiated and conductive noise. The LTC7124 is offered in a thermally enhanced, low profile 24-lead 3mm ? 5mm QFN package.Applications Battery Powered Systems Point-of-Load Supplies Portable Instruments Handheld Scanners

The AD8337 is a low noise, single-ended, linear-in-dB, general-purpose variable gain amplifier (VGA) usable at frequencies from dc to 100 MHz; the ?3 dB bandwidth is 280 MHz. Excellent bandwidth uniformity across the entire gain range and low output-referred noise makes the AD8337 ideal for gain trim applications and for driving high speed analog-to-digital converters (ADCs).Excellent dc characteristics combined with high speed make the AD8337 particularly suited for industrial ultrasound, PET scanners, and video applications. Dual-supply operation enables gain control of negative-going pulses such as generated by photodiodes or photomultiplier tubes.The AD8337 uses the popular and versatile X-AMP? architecture, exclusively from Analog Devices, Inc., with a gain range of 24 dB. The gain control interface provides precise linear-in-dB scaling of 19.7 dB/V, referenced to VCOM.The AD8337 includes an uncommitted operational current-feedback preamplifier (PrA) that operates in inverting or noninverting configurations. Using external resistors, the device can be configured for gains of 6 dB or greater. The AD8337 is characterized by a noninverting PrA gain of 2? using two external 100 ? resistors. The attenuator has a range of 24 dB, and the output amplifier has a fixed gain of 8? (18.06 dB). The lowest nominal gain range is 0 dB to 24 dB and can be shifted up or down by adjusting the preamp gain. Multiple AD8337s can be connected in series for larger gain ranges, and for interstage filtering to suppress noise and distortion, and for nulling offset voltages.The operating temperature range is ?40?C to +85?C, and it is available in an 8-lead, 3 mm ? 3 mm LFCSP.Applications Gain trim PET scanners High performance AGC systems I/Q signal processing Video Industrial and medical ultrasound Radar receivers
