ADI Launches Power Module Regulator with Up to 40V Input Voltage

Published2017.10.12 11:16

Controllable in noisy environments such as industrial robots and factory automation

Analog Devices announced the release of the LTM8065 µModule (power module) step-down regulator with a maximum input voltage of 40V (42V abs max).

This product can operate reliably from uncontrolled or fluctuating input voltages of 12V to 36V in noisy environments such as industrial robots, instrumentation, medical, factory automation, and avionics systems.

Because the Silent Switcher architecture minimizes EMC/EMI emissions, the LTM8065 passes the CISPR 22 Class B standard and can be used in noise-sensitive signal processing applications, including imaging and RF systems.

The small 6.25mm x 6.25mm x 2.32mm BGA package of the LTM8065 contains a switching regulator controller, power switch, inductor, and other supporting components. The LTM8065 solution, which requires only two 0805 capacitors and two 0603 resistors, occupies an area of about 100 mm², which is only half the size of a module solution with a similar power level.

The LTM8065 provides a continuous (3.5A peak) output current of 2.5A to a 12V input, 5V load without a heatsink or airflow at ambient temperatures up to 85°C. The output voltage is adjustable from 0.97V to 18V using a single resistor. This wide output voltage range offers excellent flexibility, allowing a single product to generate common system bus voltages of 3.3V, 5V, 12V, and 15V. The switching frequency can be controlled by a single external resistor.

ADI, 시스템 안정성 향상시키는 펄스 폭 변조 컨트롤러 출시

아나로그디바이스 (ADI)가 수상 전적이 있는ADI의 iCoupler 기술을 기반으로 제작한 펄스 폭 변조(Pulse Width Modulation, PWM) 컨트롤러 3종을 출시했다. 5kV의 통합 절연을 지원하는 이 제품군은 ADP1071-1 및 ADP1072-2 절연 동기 플라이백 컨트롤러 (synchronous flyback controller), ADP1074 절연 동기 능동 클램프 포워드 컨트롤러(synchronous active clamp forward controller)를 포함한다. 해당 제품군은 과전압 보호(overvoltage protection, OVP), 출력 추적, 에너지 고효율을 위한 경부하 모드, SR 드라이버 등 개별 부품을 필요로 하는 여러 기능을 하나로 통합하며, 광커플러를 사용한 기존 방식에 비해 보드 공간을 35% 절감하고 시스템 안정성을 크게 향상시킨다.

ADI Releases Isolated Gate Driver to Solve Power Switch Technology Issues

Analog Devices (ADI) has launched isolated gate drivers in a compact form factor. The newly released products are designed to address the high switching speeds required by power switch technologies such as SiC (silicon carbide) and GaN (gallium nitride), as well as system size constraints. At the same time, the products are designed to reliably control the switching characteristics of IGBT (insulated gate bipolar transistor) and MOSFET configurations. The ADuM4120 and ADuM4121 product families combine ADI's proven iCoupler isolation technology with high-speed CMOS and integrated transformer-coupled packaging technology to achieve extremely low propagation delay performance without compromising common mode transient immunity (CMTI) performance. Existing devices with similar functions, such as optocouplers and pulse transformers, faced difficulties in maintaining CMTI performance while reducing delay speed. However, the robust ADuM4120 and ADuM4121 are designed to increase the switching speed of new inverter architectures. For systems requiring multiple power switches, using isolated gate drivers housed in compact SOIC packages minimizes PCB layout space, thereby reducing the thermal management requirements.

ADI Launches Step-Down Regulator Capable of Current Sharing Between Devices

Analog Devices announced the launch of LTM4645, a new 25A step-down μModule (power module) regulator. The new product is characterized by its ability to share current among multiple connected LTM4645 devices. In a system architecture (N+1) where multiple LTM4645 devices (N units) are connected in parallel and at least one or more devices are used as backup (+1), when one device detects a fault and power supply needs to be cut off, the one device used as backup shares the current to ensure stable power supply to the system. For example, an ASIC with a 75A, 1V load requires three LTM4645 devices (=3 x 25A) to deliver a total of 75A. In this case, to enhance system reliability, one additional LTM4645 can be added as backup to configure a 3+1 system configuration, allowing four LTM4645 devices to share current and provide 75A even if one device fails.
