Power supply accepts wide input-voltage range
The switching power supply produces 3.3 V dc from an input voltage of 2.5 to 20 V dc with high efficiency. The circuit operates at an input voltage as low as 1.5 V...
Voltage-to-period converter offers high linearity and fast operation
The circuit converts the input DC voltage into a pulse train. The period of the pulses is proportional to the input voltage with a 50% duty cycle and a nonlinearity error of 0.01%...
Bourns introduces resistance temperature detector line engineered to meet high accuracy and long-term stability requirements
Bourns, Inc. introduced its Riedon RTDW Series Resistance Temperature Sensors...
"Flip ON Flop OFF" for 48-VDC systems with high-side switching
My Design Idea, “Flip ON Flop OFF for 48-VDC systems“, was published and referenced...
Low-power I2C/SPI-bus-to-dual-channel UART bridge from Diodes Incorporated improves automotive connectivity robustness
Diodes Incorporated announces the PI7C9X762Q, a high-performance automotive-compliant I2C/SPI-bus-to-dual-channel UART bridge...
Exponentially-controlled vactrols
Vactrols, or both an LED and a light depending resistor in a light-tight housing, are found in analog music electronics circuits like audio compressors, voltage-controlled amplifiers, voltage-controlled filters, and other applications...
On/off latch circuit
Often you want to turn on and off power to a device with a single pushbutton switch. The circuit performs this logic function with just a few parts...
Amps x Volts = Watts
Analog topologies abound for converting current to voltage, voltage to current, voltage to frequency, and frequency to voltage, among other conversions. Figure 1 joins the flock while singing a somewhat different tune...
Motor controller uses fleapower
A simple, permanent-magnet dc motor is an essential element in a variety of products, such as toys, servo mechanisms, valve actuators, robots, and automotive electronics. In many of these applications, the motor must rotate in a given direction until the mechanism reaches the end of travel...
