| The LM2575 is a ‘Simple Switcher’ from National Semiconductor, which means it’s a switch-mode controller IC that’s relatively easy to use. I...
| The circuit described here provides versatile, competent protection against extremely high inrush currents, all at a reasonable cost.
| Ultrabright LEDs are becoming increasingly attractive for use in lighting and warning-signal applications. LEDs must be operated at a consta...
| The precision current sink shown in Figure 1, which uses a Si4936 DY dual MOSFET (IC1) as a controlled load resistance, is very energy-effic...
| The IMT902 from Nanotec is a PWM chopper type sinusoidal microstep bipolar stepper motor driver. Two stepper motors can be controlled by a s...
| The circuit diagram shows a simple current source constructed from discrete components, which can deliver a constant current into a load con...
| The LT1970 from Linear Technology (www.linear-tech.com/pdf/1970f.pdf) is a power opamp with adjustable current limit, available in a 20 pin...
| There’s nothing new about a current source consisting of a transistor, a resistor and an LED to provide the reference voltage. However, what...
| All simple constant-current sources generally operate on the same principle: a current is allowed to flow through a resistance and some sort...
