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.

DC-DC Converter Family Adds Tighter Voltage Regulation

Vicor has added 25 new products to its family of DC-DC converter modules (DCMs) with tighter output voltage regulation of ±1%. With high power densities of 1,032 W/inches-squared, the new series allows engineers to drive loads requiring tighter regulation with minimal additional circuitry or downstream components.

The DCM ChiP (Converter housed in Package) is a DC-DC converter module that operates from an unregulated, wide range input to generate an isolated, regulated DC output. With its high frequency zero-voltage switching (ZVS) topology, the DCM converter consistently delivers high efficiency across its entire input voltage range.

The new DCMs are used broadly across defense and industrial applications that require tighter output voltage regulation. These applications include UAV, ground vehicle, radar, transportation and industrial controls. The DCM ChiPs are available in M-grade, which can perform at temperatures as low as -55°C.

Module Combines Isolated Data Comms and Power in One Device

Murata Power Solutions has announced the introduction of the NMUSB2022PMC, a surface mount powered data isolator module that conveniently provides dual port USB data and power isolation from a single upstream port. When used in conjunction with a USB host, a single NMUSB202PMC module counts as two USB hubs for cascaded applications and provides full 5V/500mA power to each downstream port. 250 VRMS reinforced isolation provides safety, immunity to EMI and breaking of ground loops.

The is NMUSB2022PMC is fully compliant with USB 2.0 specification, which enables hassle-free, “plug and play” operation with any USB-compatible device. It can do automatic switching between full-speed (12 Mbps) and low speed (1.5 Mbps) operation. Operating temperature ranges from -40°C to +85°C.

The device enables USB isolation function with a single SMT component. Users may power any USB compatible device from the NMUSB module. The data isolation function included with the DC-DC module adds value and convenience to the user and also eases system approval for medical systems safety certifications. Applications include industrial control for isolating sensors and medical environments, where USB is becoming common for low cost sensing and communication but isolation is necessary for safety and noise immunity. It is also well suited for harsh environment data communication and sensor communications.

DC-DC Converter Family Targets Modern Railway Systems

Vicor has released its next generation of DCMs with a family of wide input range (43 V to 154 V input) 3623 (36 mm x 23mm) ChiPs with power levels up to 240 W and 93% efficiency, targeted at new rail transportation and infrastructure applications. Modern rail infrastructure requires a wide range of DC-DC converters to power a variety of new services for both freight and commuter markets.

Commuter rail systems require mobile office communication capabilities with the infotainment capabilities of home. Freight rail systems require monitoring and control capabilities to assure the safe and timely delivery of all goods onboard. While both commuter and freight systems demand reliable and high-performance power systems for the necessary safety and security measures (onboard and at station.)
The DCM is an isolated, regulated DC-DC converter module that can operate from an unregulated, wide range input to generate an isolated DC output. These new ChiP DCMs simplify power system designs by supporting multiple input voltage ranges in a single ChiP. With efficiencies up to 93% in a ChiP package less than 1.5 in2, these DCMs offer engineers leading density and efficiency.
