60-V input, dual-output DC/DC controller sports
programmable loop compensation, I²C-based PMBus interface
MILPITAS, CA – August 12, 2015 – Linear Technology Corporation announces the LTC3886, a 60V input dual output synchronous step-down DC/DC controller with programmable loop compensation and I²C-based PMBus interface. This controller employs a constant-frequency, current-mode architecture with programmable output voltage up to 13.8V. The LTC3886 is ideal for harsh environments requiring a high input […]
EPC introduces fast, small monolithic gallium nitride power transistor half bridge operating over 2 MHz
EPC announces the EPC2106, an enhancement-mode monolithic GaN transistor half bridge. By integrating two eGaN® power FETs into a single device, interconnect inductances and the interstitial space needed on the PCB are eliminated. This increases both efficiency (especially at higher frequencies) and power density, while reducing assembly costs to the end user’s power conversion system. […]

Transimpedance Amplifier: Which power chain
should I consider to maximize performance?
The behavior of a transimpedance amplifier relates directly to the performance of its power supply. Here a low-dropout design with a high power-supply-rejection-ratio can help. Xavier Ramus, Product definer, Linear Regulator and Supervisors group Texas Instruments Inc. Transimpedance amplifiers (TIA) are used in many applications, from automotive collision avoidance light detection and ranging (LIDAR) systems […]
Astrodyne TDI offers rugged, digitally controlled test rectifier for cathodic protection
Astrodyne TDI, a global developer and manufacturer of specialized power solutions, has introduced a rugged and portable test rectifier. The Lightweight Test Rectifier (LTR), part of the Defender product line, is designed to test impressed current cathodic protection (ICCP) installation sites. Weighing less than 25 pounds and housed in a durable, compact case, this new […]
GaN power circuit with integrated bootstrap FET
Designed specifically for resonant wireless power transfer applications, the EPC2107 (100 V) and EPC2108 (60V) eGaN power integrated circuits include monolithic half bridge and integrated bootstrap functions for A4WP compliant Class 2 and Class 3 applications. This integration eliminates gate driver induced recovery losses as well as the need for a high-side clamp. These devices […]
Basics of cooling transistors, IGBTs,
and power FETs with heat sinks and PCBs
By Chris Francis When designing any electronics that consumes a significant amount of power you need to consider where that power is going to go. With power electronics –such as IGBTs, power FETs, or power transistors — you might be expecting most of it to end up in your load but there will be some which doesn’t. Even […]
SMD fuse with 1.5-kA breaking capacity gets UL, VDE stamps
SCHURTER’s Universal Modular fuse, UMT-H, offers a 1500-A breaking capacity at rated voltages of 277 VAC / 250 VDC. The compact, high performance fuse now has VDE approval in addition to UL approval. This time-lag fuse provides overcurrent and short circuit protection in various industrial control applications, including intrinsically safe applications. The “intrinsic safety” method […]
