.. value of V IN is required by the regulator, an inexpensive LDO can provide an appropriate U 2 supply. I grant that this design might be overkill, but I wanted to see what might be required to meet the goals I set. But who knows, ...
.. operation, including 3 µA by the undervoltage-lockout, voltage-sensing divider and 17 µA by IC 1 . If your design needs high-temperature operation, note that the gate-current output of IC 1 is relatively limited. Your ...
.. part is in shutdown so the resistive divider networks on the UVSET and OVSET pins do not load the input voltage. In this design, the UVSET pin is tied to the TERM pin so the MOSFETs are turned on when the device reaches its minimum ...
.. According to the datasheet, the features of the DK106 are as follows: 85 V 265 V wide-range AC power input. Double chip design with bipolar junction transistor (BJT) to save cost. Large-scale MOS digital circuit design with E class BJT ...
.. a PCB, purchased the (mostly) surface-mount components, loaded and re-flow soldered them onto the PCB, and then tested the design. Figure 1. VFC design that operates from 100 kHz to beyond 100 MHz with a single 5-V supply, providing ...
.. conducting some tests, it was found that the circuit operates quite stable, and the received sound is clear and sharp. To design the schematic and PCB, I used Altium Designer 23 and shared the project with my friends to get their feedback ...
.. been interest recently here in the land of Design Ideas (DIs) in a family of simple interface circuits for pulse width modulation (PWM) control of generic ...
.. voltage to approximately 3 V, which also limits the drive voltage to Q 1 ’s gate. The PCB (printed-circuit-board) design and the choice of coupled inductors for this power supply are critical for good performance. For the power ...
