released a high voltage non- isolated synchronous step-down switching regulator controller that drives an all N-channelMOSFET power stage. Its 4V to 140V (150V absmax) input voltage range is designed to operate froma high input voltage source or froman input


from0.8V to 60V at output currents up to 20amps with efficiencies as high as 96%. This part draws only 40µA in sleepmode with the output voltage in regulation, ideal for always-on systems. An internal charge pump allows for 100%duty cycle operation in dropout, a useful feature when powered froma battery during discharge. The power ful 1Ω

N-channelMOSFET gate drivers can be adjusted from5V to 10V to enable the use of logic- or standard-level MOSFETs tomaximise efficiency. To prevent high on-chip power dissipation in high input voltage applications, this device includes an NDRV pin which drives the gate of an optional external N-channelMOSFET acting as a low dropout linear regulator to supply IC power. The EXTVCC pin permits this device to be powered fromthe output of the switching regulator or other available source, reducing power dissipation and improving efficiency.


The LTC3895 operates with a


selectable fixed frequency between 50kHz and 900kHz regulation. www.linear.co m

A 10-bit PCIe high-speed digitizer running at 10GS/s has been launched by Keysight Technologies, Inc. With a very-high dynamic range and 10-bit resolution across a wide 2.5GHz bandwidth, the high-speed digitizer allows the capture of fast transients with high fidelity. This ADC card is designed for embedded OEM applications, such as medical research, analytical time-of-


flight (MS-TOF), environmental monitoring (LiDAR), ultrasonic non-destructive testing (NDT), semiconductor testing and distributed strain temperature sensor (DSTS). Furthermore, the new device is ideal for advanced physics experiments using single-shot or event-based applications. The new U5310A high-speed digitizer features two channels with 10-bit resolution, simultaneous sampling


at up to 5GS/s, and 10GS/s in interleaved mode. With a DC up to 2.5GHz bandwidth, this digitizer provides on- board real-time averaging at full sampling rate and large 4GB memory. Keysight developed new proprietary ICs for the U5310A. In particular, the low distortion and low noise LDNA


front-end amplifier IC to drive the ADC. This key component provides single ended to differential outputs with a distortion from 10 to 15dB lower than the distortion of the ADC—therefore overall performance is not impacted. The company also designed a low noise dedicated QMCK clock IC with very low 25 fs jitter. This specific IC drives the two ADCs, minimising jitter. Moreover, the TRAC trigger IC provides time precision of 15ps RMS. The averager (-AVG) firmware ensures accumulation of a large number of triggers for synchronous real-time sampling at 5GS/s on two channels and 10GS/s when interleaved. Innovative features, such as the programmable self-trigger output, optimises the signal-to-noise ratio and increases the ability to measure very small peaks accurately. This new PCIe high-speed digitizer focuses on interoperability, reusability and upgradability with other U53xxA digitizers. www.keysight.com
