Two Methods for Push Button Controlled Power Switch April 30, 2012 Power Supply Circuits MAX1703 Single-Cell Boost Converter Circuit September 18, 2013 When you design a circuit with only a single-cell battery, you will need boost-converter to provide enough voltage for most […] ...
There are many ways to do it, but we chose to use the transistor as a switch. It has a simple concept: by turning off (OFF) or turning on (ON) a load that uses 12V with a control voltage level of 3.3V. As shown on the circuit below. Simplemotion sensor circuitusingTransistor ampl...
Hence, if in the preliminary calibration of the circuit is implemented using a precisely identified 1000 pF capacitor attached to terminals X-X, and the range switch positioned to position B, and calibration pot R11 adjusted to achieve an exact full-scale deflection on the meter M1, then the ...
I have a wireless door bell I am using for a mailbox alarm with a mercury switch for activation. The receiver sounds a chime and flashes an LED but I want the LED to stay on until I reset it. Should I use a latching relay or transistor circuit? Thanks Submitted by Maddy on Sat, ...
As a switch-mode voltage regulator, this circuit gives higher efficiency than linear regulator type. Using the National Semiconductor LM1575-5.0, this circuit can be used to convert 28VDC To 5VDC with efficiency of >80%. This circuit can be used as a 5V source @ 1A. Here is the schematic...
Please refer to Functional Block Diagram for more details. The peak current of high-side switch is limited by a clamped maximum peak current threshold which is constant. So the peak current limit of the high-side switch is not affected by the slope compensation and remains constant over the ...
The two output square and sine can be selected using switch S1 to the input of IC2 which amplifies it to drive the speaker. POT R4 can be used for tone adjustment. Simple Alarm Circuit Diagram with Parts List Alarm Circuit Diagram
7.2 Functional Block Diagram * Active Inductor Patent Number 5,514,947 † Active Capacitor Patent Number 5,382,918 7.3 Feature Description 7.3.1 Switch Output This is the output of a power MOSFET switch connected directly to the input voltage. The switch provides energy to an inductor, an ...
When the HS switch is turned off by the control logic, the LS switch is turned on after an anti-shoot-through dead time. Inductor current discharges through the LS switch with a slope of –VOUT / L. The control parameter of a buck converter is defined as duty cycle D = tON / TSW,...
