DC Power source switching methods
A common situation is when you may have more than one possible power source to power some electronics. For example a mains AC-DC adaptor or a battery may be used to power an electronic device. In the past the simple solution was to use a DC power connector with a built in physical switch such […]
SLN3 molded current sense resistor offers 3-W power rating
KOA Speer Electronics introduces the new SLN3 molded current sense resistor, featuring a 3-Watt power rating in 4528 size. The molded resin resistor provides excellent dimensional accuracy, mountability and shock resistance. Due to its metal plate terminal electrode, it also offers excellent terminal strength, heat and shock resistance and solderability. KOA Speer’s SLN3 resistor has […]

This series now covers critical applications in Aerospace, EV/HEV, Rugged Systems, Industrial, and Telecom/Datacom. DCMs provide nominal input voltages of 24, 28, 48, 270, 290, and 300 […]
Thermal management and cost of ownership in power systems
by Jerry Hovdestad, Director COTS Engineering, Behlman Electronics To an engineer, power management is also thermal management. Excess heat generated by power systems places additional burdens on their cooling technology. Even the most efficient system will have performance and reliability issues if served by an inefficient cooling method. Power and heat are two sides of […]
Buck dc/dc converter provides 8 A for four outputs
Linear Technology Corporation announces the LTC3371, a highly integrated general-purpose power management solution for systems requiring multiple low voltage power supplies. The device features four synchronous buck converters, each powered from independent 2.25V to 5.5V inputs, and each configurable to share up to four of eight available 1A power stages. With eight unique output current […]
20-A step-down regulator optimized for low V IN/low V OUT
Linear Technology Corporation introduces the LTM4639, a 20A DC/DC step-down µModule® (micromodule) regulator capable of converting 2.5V to 7V main-power system rails to point-of-load voltages as low as 0.6V with optimum efficiency. In complex rack-mount systems, improved voltage conversion efficiency results in savings in energy consumption, thermal management and equipment size. Applications include cloud-based equipment […]
Programmable power supply series extends to 800W 650V output
TDK Corporation announces the introduction of 800W high voltage models to TDK-Lambda’s Z+ series of programmable DC power supplies. The series is now available with output voltages of -10, 0-20, 0-36, 0-60, 0-160, 0-320 and 0-650VDC with output powers of 200 to 800W. These higher voltages address the requirements for applications such as deposition processes, […]
Choosing a brushless DC motor driver
By Chris Francis Brushless DC motors (BLDC motors) are quite different to drive compared to brushed DC motors. With a brushed DC motor you simply apply a voltage or pulse width modulated voltage and the motor will start turning (if possible) and increase speed with reducing torque until the torque/speed match the load. A brushless […]
