45W USB-PD SMPS REFERENCE DESIGN DELIVERS 21.5W/IN3

The REF_XDPS21071_45W1 from Infineon is a 45W USB-PD type C charger reference design in a small form factor. The reference design has been developed to demonstrate the performance by meeting various regulatory limits as well as allowing for small form factor designs. It features Infineon’s digital flyback controller XDPS21071, 700V CoolMOS™ P7 Superjunction MOSFET (IPD70R360P7S), OptiMOS™ PD synchronous-rectification MOSFET […]

PINET — ONE SMALL PROJECT GROWS UNEXPECTEDLY

A few years ago, [Gregory Sanders] aka [Dr Gerg] had one simple wish in mind when he started what is now the PiNet project — to know whether his garage door was open or closed. Instead of searching out off-the-shelf solutions, he looked at the project as a learning opportunity. After picking up Python, he built a

A CLOSE LOOK AT USB POWER

It’s not a stretch to say that most devices these days have settled on USB as their power source of choice. While we imagine you’ll still be running into the occasional wall wart and barrel jack for the foreseeable future, at least we’re getting closer to a unified charging and power delivery technology. But are

ISABELLENHÜTTE INTRODUCES NEW RANGE OF 1 – 6MΩ RESISTORS IN SMALLEST CHIP SIZES AVAILABLE ON THE MARKET

Isabellenhütte has developed a new range of precision resistors in standard sizes with resistances ranging from 1 to 6 mOhm for applications which require small and low-ohmic shunts. In terms of their construction, the components are also less complex than the current ISA-PLAN®resistance families. And yet, they offer the same performance quality: very good long-term

LTC4162 Charges batteries from Solar Cells using MPPT

The first step to designing a battery charger is choosing a battery charger IC from the vast field of available solutions. To make an informed decision, a design team must first clearly define the battery parameters (chemistry, cell count, etc.) and the input parameters (solar, USB, etc.). The team must then search for chargers that

POWER TO THE PI 4: SOME CHARGERS MAY NOT MAKE THE GRADE

The Raspberry Pi 4 has been in the hands of consumers for a few days now, and while everyone seems happy with their new boards there are some reports of certain USB-C power supplies not powering them. It has been speculated that the cause may lie in the use of pulldown resistors on the configuration channel
