Module protects USB circuits from ground-to-ground voltage differentials, large common-mode transients
Linear Technology Corporation introduces the LTM2894, a USB µModule® (micromodule) reinforced isolator that guards against ground-to-ground voltage differentials and large common mode transients. A rugged interface and internal isolation makes the LTM2894 ideal for systems implementing USB in harsh industrial or medical environments where protection from high voltages is required. The LTM2894 separates grounds by […]

Half-bridge drivers work with three-phase motor controllers
Infineon Technologies AG adds two power boards to the family of iMOTION™ Modular Application Design Kits (MADK). The two half bridge boards complement the compact and flexible evaluation system providing a scalable design platform for 3-phase motor drives in the range from 20 W to 300 W. The MADK aims at applications in the field […]
MELF resistor technology provides cooler operating temperatures at full-rated power
Stackpole’s MLF / MLFM is a series of metal film, surface mount MELF resistors. The MELF technology provides cooler operating temperatures than flat chip resistors at full rated power. For example, the MLFM1 will typically run more than 70 degrees C cooler than the equivalent 1W 2512 size flat chip resistor and has a smaller […]
30-A to 180-A regulator module includes inductor, support components in BGA package
Linear Technology introduces the LTM4647, a 30A step-down µModule (power module) regulator. The LTM4647 includes the inductor, MOSFET, DC/DC controller and supporting components in a 9mm x 15mm x 5.01mm BGA package. The device’s conversion efficiency from 12VIN to 1VOUT at 30A is 87%, when delivering a full 30A continuously without a heat sink or […]
60W waterproof LED driver with PFC delivers 200~400VAC input
In order to meet the 277VAC and 347VAC input requirement in North America region, MEAN WELL specially unveils the new 60W LPFH-60 and LPFH-60D (with built-in 3 in 1 dimming function) series which accept 200VAC~400VAC input.

Ultra-compact open-frame ac-dc power supplies squeeze into space-constrained apps
A family of ultra‑compact ac-dc power supplies in an open frame SIP package include 3-W and 5-W configurations. Developed by CUI Inc. and called the PBO series, they measure as small as 35 x 11 x 18 mm (1.38 x 0.43 x 0.71 in), occupying less board real-estate than other power solutions. The 3-W models […]
Octal high-side switch and driver controls inductive loads
Designers of industrial controllers can safely drive and demagnetize any inductive load for Industry 4.0 applications with the MAX14913 octal high-side switch and driver from Maxim Integrated Products, Inc. . With a unique, innovative, safe-demagnetizing clamp on each output, it easily and reliably interfaces low-voltage digital signals to 24V output-control lines. For most industrial applications, engineers need […]
Isolated RS-485 µModule transceiver meets medical IEC 60601-1 requirements
Linear Technology Corporation introduces the LTM2885, an isolated RS485 µModule® transceiver for guarding against large ground-to-ground differentials. Many industrial, utility, medical, military, and intrinsic safety applications require isolation components with increased voltage and spatial separation for human safety. The LTM2885 provides 6500VRMS reinforced isolation between the logic level interface and the transceiver bus pins, far […]
