DC-DC Modules Boast Wide Voltage Range, Small Footprint

Maxim Integrated Products has announced four new micro-system-level IC (“uSLIC”) modules. The MAXM17552, MAXM15064, MAXM17900 and MAXM17903 step-down DC-DC power modules join Maxim’s extensive portfolio of Himalaya power solutions, providing the widest input voltage range (4 V to 60 V) with the smallest solution sizes.

While miniaturization remains the trend for an array of system designs, many of these designs also require a wide range of input voltages. For example, supply voltages in factory automation equipment are susceptible to large fluctuations due to long transmission lines. USB-C and broad 12 V nominal applications require up to 24 V of working voltage protection against transients due to hot plugging of supplies and/or batteries.
The newest Himalaya uSLIC power modules extend the portfolio’s range up to 60 V versus the previous maximum of 42V and come in a solution size (2.6 mm x 3.0 mm x 1.5 mm) less than half the size of the closest competitive offering. The modules feature a synchronous wide-input Himalaya buck regulator with built-in FETs, compensation and other functions with an integrated shielded inductor. Having the inductor in the module simplifies the toughest aspect of power supply design, enabling designers to create a robust, reliable power supply in less than a day.

The newest uSLIC modules are:

• MAXM17552, a 4 to 60V, 100mA module with 100 to 900kHz adjustable switching frequency, 82% efficiency (24V VIN at 5V/0.1A) and external clock synchronization in a 2.6mm x 3mm x 1.5mm package
• MAXM15064, a 4.5 to 60V, 300mA module with 500kHz fixed frequency, 82% efficiency (24V VIN at 5V/0.1A) and built-in output voltage monitoring in a 2.6mm x 3mm x 1.5mm package
• MAXM17900, a 4 to 24V, 100mA module with 100 to 900kHz adjustable switching frequency, 86% efficiency (12V VIN at 5V/100mA), external clock synchronization and built-in output voltage monitoring in a 2.6mm x 3mm x 1.5mm package
• MAXM17903, a 4.5 to 24V, 300mA module with 500kHz fixed switching frequency, 77% efficiency (12V VIN at 3.3V/300mA) and built-in output voltage monitoring in a 2.6mm x 3mm x 1.5mm package

The uSLIC modules can be purchased for the following prices: MAXM17552 for $2.53, MAXM15064 for $2.78, MAXM17900 for $1.39, and MAXM17903 for $1.48 (1000-up, FOB USA); they are also available from authorized distributors. The MAXM17552EVKIT#, MAXM15064EVKIT#, MAXM17900EVKIT# and MAXM17903EVKIT# evaluation kits are available at $29.73 each.

COM Express Type 6 Card Sports AMD Ryzen V1000

Congatec has introduced the conga-TR4 COM Express Type 6 module based on the new AMD Ryzen Embedded V1000 processors. AMD Ryzen Embedded V1000 processors deliver up to 3X more GPU performance than competitive solutions, and up to 2X increase in performance over previous generations . With a TDP that is scalable from 12 W to 54 W, Congatec products based on these new processors can benefit from multiple performance leaps across the TDP range and enormous optimization potential with regards to size, weight, power and costs (SWaP-C) at high graphics performance.

The new Congatec COM Express basic modules are designed for the development of embedded computing systems with impressive graphics performance for applications such as medical imaging; professional broadcasting, infotainment and gambling; digital signage; control rooms and video surveillance; optical quality control and 3D simulators. Other applications include smart robotics and autonomous vehicles that use deep learning to optimize their situational awareness.

The new conga-TR4 high-performance modules with COM Express Type 6 pinout are based on the latest AMD Ryzen Embedded V1000 multi-core processors. These modules offer up to 52% more processor performance, reaching up to 3.75 GHz. Thanks to symmetrical multiprocessing, they also provide particularly high parallel processing performance. They support up to 32 GB energy-efficient and fast dual-channel DDR4 memory with up to 3200 MT/s and optional ECC for maximum data security.

The new integrated AMD Radeon Vega graphics with up to 11 compute units marks the cutting edge of embedded graphics. It supports up to four independent displays with up to 4k UHD resolution and 10-bit HDR, as well as DirectX 12 and OpenGL 4.4 for 3D graphics. The integrated video engine enables hardware-accelerated streaming of HEVC (H.265) video  in both directions. Thanks to HSA and OpenCL 2.0 support, deep learning workloads can be assigned to the GPU. In safety-critical applications, the integrated AMD Secure Processor helps with hardware-accelerated encryption and decryption of RSA, SHA and AES.

The new conga-TR4 is also the first Congatec COM Express Type 6 module to allow a complete USB-C implementation on the carrier board including USB 3.1 Gen 2 with 10 Gbit/s, Power Delivery and DisplayPort 1.4, for example to connect external touchscreens with a single cable. Further performance-oriented interfaces offered, includes 1x PEG 3.0 x8, 4x PCIe Gen 3 and 4x PCIe Gen 2, 3x USB 3.1 Gen 2, 1x USB 3.1 Gen 1, 8x USB 2.0, 2x SATA Gen 3, 1x Gbit Ethernet. I/Os for SD, SPI, LPC, I²C as well as 2x legacy UART from the CPU and High Definition Audio round off the range of interfaces.

The supported operating systems include Linux, Yocto 2.0 and Microsoft Windows 10, or optionally Windows 7. Congatec provides an extensive range of passive and active cooling solutions for workstation designs up to 54W performance, application-ready carrier boards as well as best practice carrier board layouts and circuit diagrams, such as for USB-C implementations, to help simplify the design-in of the modules. Congatec also offers the development of custom carrier boards and module variants.
