Texas Instruments’ switching noise on audio reduction using spread spectrum tech. Link here Automotive systems have many regulations and requirements, from electromagnetic interference (EMI) to thermals to functional safety, but one consideration that stands above the rest when it comes to immediate consumer dissatisfaction is audible noise. In this technical article, I’ll discuss common sources […]

9V to 48V DC-DC converter
Konstantin Dimitrov over at Electronics Lab writes: This project is a 8-12Vdc to +48Vdc DC-DC converter based on MC34063 switching regulator. It’s a simple project of a DC-DC converter to make a phantom power supply for professional microphones. It can deliver 15-20mA at 48VDC. It ‘s based on MC34063 DC-DC step-up, step-down and boost converter. […]
Simple and efficient 12V to 5V convertor
Fcobcn shared his simple and efficient 12V to 5v converter. It’s based around the TL2575 buck IC, and can output 1 amp of current. I’m using a TL2575 from ti, wich has a max efficiency of 88%, 1A, works quite well, previously were using a 7805 wich needed heat sinking. There’s apparently no heat coming […]
Voltage regulator chip roundup
McZ and rsdio tipped us to a bunch of new and wonderful voltage regulator chips. Tiny regulators, high current regulators, and high voltage regulators. TPS84620: 4.5V to 14.5V input, 6A switching regulator needs only three external parts MAX15040: 2.4V to 3.6V input, 4A switching regulator is the smallest yet MAX15050/MAX15051: 2.9V to 5.5V input, 4A […]
