  1. The circuit in Figure 1 provides a 20-MHz square wave across a set of highly capacitive ion-deflection plates in an experimental instrument. To get the required deflection, the plate voltage must be 20 to 30 V, much higher voltage than conventional ...

  2. Many applications require the design of custom analog filters (Reference 1). The application for this design required simple and low-cost I/O filters for PLC (power-line communications), where low power consumption is a crucial factor. Figure 1 ...

  1. Because of internal circuit-breaker delay and limited MOS-gate pulldown current, many hot-swap controllers do not limit current during the first 10 to 50 µsec following a shorted output. The result can be a brief flow of several hundred ...

  2. For safety reasons, a motor that drives a safety-critical electromechanical assembly often includes an electromagnetic brake on its drive shaft. The brake typically comprises a solenoid coil that actuates a mechanical clutch, and, when you power ...

  4. Power-supply designers can choose from a plethora of available positive buck regulators that can also serve as negative boost DC/DC converters. Some buck regulators have a negative-feedback reference voltage expressly for this purpose, but ICs that ...

  5. Most of today’s microcontrollers are powered with a DC voltage of 3.3 V or less. Batteries are involved for low-power embedded systems that have intermittent uses. For permanent usage, designs usually include a mains supply (with transformer ...

  6. Stepper motors are synchronous motors that step at the pulse rate of the driving signal. For the motor to move quickly, the stepping rate must be fast. However, because of motor and load inertia, the motor often cannot go from 0 rpm to the desired ...

  7. A perennial challenge in power-supply design is the safe and speedy discharge, or “dump,” at turn-off of the large amount of energy stored in the postrectification filter capacitors. This energy, CV 2 /2, can usually reach tens of ...

  8. In a standard dc-dc converter, a resistor divider typically defines a fixed output voltage. However, applications like programmable output voltage power supplies and motor control circuits require dynamic control of the dc-dc converter's output ...
