Electronic circuits frequently require zero-ohm jumpers for ease of manufacture or to make trace routing easier. Some of these applications require current handling that exceeds the capabilities of general-purpose or high current jumpers. Stackpole’s HCJ series offers more than double the current rating of comparable high current jumpers. The HCJ current ratings range from 5.8A for […]

Reverse-boost converter. excels in high-efficiency light-load apps
EPC announces the availability of the EPC9162, a bi-directional buck or reverse-boost converter. This demonstration board features the 100 V EPC2052 for the synchronous converter and the EPC2038 in the synchronous bootstrap FET circuit. The EPC9162 is by default programmed as a boost converter operating at 12 V input to 60 V/50 W output. However, […]
PXI, multi-cell battery simulator modules target automotive and aerospace applications
Pickering Interfaces launched a new family of battery simulator modules, ideal for Electric Vehicle (EV) battery stack emulation in Battery Management Systems (BMS) test applications. The 41-752A (PXI) and 43-752A (PXIe) modules enable direct voltage and current readback either programmatically or using Pickering’s soft panel control. Each cell simulator is highly accurate, specified at ±5 mV from 1 […]
Bay interface card increases maxim GPS-series power system capacity to more than 20,000 A
To help meet the need for more power from smaller-capacity rectifiers, ABB Power Conversion has developed a new bay interface card, BIC-11. With the upgraded bay interface card, maximum GPS-series power system capacity can be increased from 11,000 amps (A) to more than 20,000A. The bay interface card enables a single system controller to interface […]
Dual MOSFETs deliver ±40V/±60V withstand voltage required for 24-V input
ROHM Semiconductor announced the QH8Mx5/SH8Mx5 series of dual-MOSFET products (N-channel + P-channel) featuring ±40V/±60V withstand voltages. The devices are ideal for driving motors in base stations (cooling fans) and industrial applications, such as factory automation equipment requiring 24V input. In recent years, MOSFETs have become increasingly required to ensure sufficient margin against voltage fluctuations by providing 40V and 60V withstand […]
How to keep transients from disrupting low-power circuits
It can be challenging to give a highly dynamic load a stable voltage when the power supply sits several feet away from the device under test. Bill Griffith • Keysight Technologies Today’s integrated circuits put a highly dynamic load on their power supply. This behavior poses a challenge during testing when IC power comes from […]
100-W railway / industrial DC-DC converter sports 12:1 input range
TRACO POWER announces the new TEP 100UIR family of 100 Watt DC/DC converters in a fully encapsulated, compact Quarter brick footprint with an ultra-wide 12:1 input range for harsh environments in railway and industrial applications. The ultra-wide 12:1 input voltage range (9-75 / 14-160 VDC) lets system builders reduce design variations required to satisfy varying […]
Clearing up confusion about tracking multiple current levels
Multichannel power monitors help simplify battery-based systems employing multiple current sensors. Mitch Polonsky • Microchip Technology Inc. Designers of power systems can be forgiven for having some confusion about power monitors. Some of them may even be using a multichannel power monitor without knowing it. That’s because, regrettably, several different phrases are used to refer […]
Inside a modern power management IC
PMICs today do a lot more than just regulate voltages. Here’s a look at high-end functions these devices provide. Narasimhan Trichy • Qorvo Superior power management and high efficiency have become essential as electronics have become increasingly smaller and more streamlined. The reduction of power dissipation and consequent heat and thermal issues is critical to […]
Harvesting energy from ocean waves
Efficient power conversion technology now makes buoy systems practical for powering real-world devices. Autonomous offshore power systems (AOPS) now capture mechanical wave energy and convert it into usable power for a wide range of oceanic applications such as offshore oil and gas exploration and production, offshore carbon sequestration, oceanographic research, aquaculture and homeland defense. An […]
