    Converting 1.5V from AAA cell to 0.8V output

    Hi all, I'm designing a circuit that needs to take 1.5V from two AAA cells in parallel and outputs 0.8V to a DPDT toggle switch (on-off-on) that connects the load to +0.8V, 0V, and -0.8V depending upon the switch position. The output current would ideally be able to reach up to 1.5A for safety...

    How to improve efficiency of Full-Bridge SMPS?

    Hello, I am designing full-bridge SMPS with a linear voltage stabilizer in LTspice. When I was making measurements I discovered that the maximum efficiency of my power supply is around 30% at full load. Project assumptions: Input voltage: 230 AC Output voltage: 0 - 25 V DC Output current: 5 A...
