It’s often necessary to connect point-of- load (POL) dc/dc power supply modules in parallel to get a sufficiently high-current output for applications such as test instruments, blade servers, and so ...

To improve efficiency in high-power applications, voltage regulators can be used in parallel to double output current capability—if a means of forcing current sharing is provided. One circuit approach ...

Automotive, industrial, and FireWire peripherals all call for high-efficiency, space-saving power supplies with high current capabilities at very high voltages. The problem is that high-voltage, ...

Another important concern is the balance of currents that flow in multiple strings. We know that two or three strings of LEDs will have different combined forward voltages. The LED driver will deliver ...

Parallel Circuit Calculations provides a comprehensive overview of the rules and formulas used to calculate electrical quantities and capacity. Using a direct current parallel circuit as an example, ...

Last time we looked at Spice models of a current sink. We didn’t look at some of the problems involved with a simple sink, and for many practical applications, they are perfectly adequate. However, ...

Whatever your applications design(s) — digital multimeter, oscilloscope, on-board charger (OBC), plug-in battery for hybrid or electric vehicles, power supply for a motor drives, etc. — it needs to ...

If you got your start in electronics sometime after 1980 your first project might well have been to light up an LED. Microcontroller projects often light up an LED, too, and a blinking LED is ...
