ADI Launches Step-Down Regulator Meeting CISPR 22 Class B Requirements

Published2017.04.13 14:49

Operation in noisy environments such as factory automation and aviation systems

Minimizing EMC/EMI emissions enables utilization in various signal processing applications.

Analog Devices has released the µModule® step-down regulator LTM8073, which supports an input voltage range of up to 60V (up to 65V abs).

This regulator can operate safely in noisy environments such as communication infrastructure, factory automation, industrial robotics, and aviation systems using uncontrolled or fluctuating 24V to 48V input voltages.

Analog Devices’ proprietary Silent Switcher® architecture applied to this product minimizes EMC/EMI emissions, allowing the LTM8073 to comply with CISPR 22 Class B requirements and be used in various signal processing applications, including imaging and RF systems.

The output voltage can be adjusted from 0.8V to 15V using a single resistor. Because it can provide such a wide output voltage range, a single product can generate common system bus voltages of 3.3V, 5V, 12V, and 15V. The efficiency for 24VIN to 5VOUT at 3A is 90%.

The LTM8073 can provide an output current of 3A without a heat sink or airflow up to an ambient temperature of 85°C. Since a SHARE pin is provided to share current, parallel driving for a larger current supply is possible.

The LTM8073 integrates a switching regulator controller, power switch, inductor, and other supporting components into a 6.25mm x 9mm x 3.32mm BGA package, allowing the design to be completed by adding only input and output capacitors and a few small resistors.

ADI Launches 28nm CMOS LiDAR Technology Platform

Analog Devices has launched the Drive360™ 28nm CMOS RADAR technology platform, which is built on its ADAS (Advanced Driver Assistance System), MEMS, and RADAR technology portfolio. Analog Devices is the first to provide automotive RADAR technology based on the latest 28nm CMOS process. The Drive360™ RADAR platform delivers best-in-class RF performance for the latest safety and autonomous driving applications. This RF performance is superior to the current class-leading SiGe (silicon germanium) based platform, enabling vehicles to gain time to recognize and avoid small objects at greater distances.

ADI Launches 32-Bit SAR ADC with Maximum Dynamic Range

Analog Devices announced the launch of the LTC2500-32, an ultra-high-precision 32-bit SAR (successive approximation register) ADC (analog-to-digital converter). The LTC2500-32 represents a new implementation approach for precision measurement applications. It combines high accuracy with Linear Technology's proprietary SAR ADC architecture along with a flexible integrated digital filter to optimize system signal bandwidth and facilitate analog anti-aliasing filter requirements. The LTC2500-32 simultaneously provides (1) 32-bit low-noise digital filtered output (achieving a maximum dynamic range of 148dB) and (2) 32-bit 1Msps zero-latency output (consisting of an overrange detection bit, 24 bits representing the input voltage difference, and 7 bits indicating common-mode input voltage).
