The project published here is a high-voltage adjustable regulator with an output 48 V DC from an input supply of 125V DC. The circuit is capable to drive load current up to 500mA. This regulator circuit designed for use in high-voltage applications where standard bipolar regulators...

The STEVAl-ISA171V1 reference design from STMicroelectronics implements a 15 W ac-dc power supply designed in quasi-resonant flyback topology for a wide-range input voltage. Its key features are its small size and minimal bill of material, high efficiency and low standby...

The MAX17662BEVKITB# evaluation kit (EV kit) from Maxim Integrated Products provides a proven design to evaluate the MAX17662B high-efficiency, synchronous step-down dc-dc converter. The EV kit provides 5V/2A at the output from a 6.5V to 36V input supply. Applications are expected to...

Being able to turn a USB-C supply to a variable power supply is certainly a big deal for a simple ingenious board like the ZY12PDN board shared by Keneth Finnegan on his twitter handle recently. The ZY12PDN is a simple STM-powered adapter board that turns a USB-C supply to a universal...

Matthew Millman has published a new project: For a number of years now I’ve had a couple of high powered switching power supply units made by Power-One. They’re typically found in I.T. equipment and provide a single output rail of either 12 V or 48 V with a very high current...

GaN Systems and ON Semiconductor announced the availability of the NCP13992UHD300WGEVB, the world’s highest power density 300W ac-dc adapter reference design using GaN Systems’ 650V, 15A gallium-nitride (GaN) E-HEMTs and multiple ON Semiconductor controller and driver ICs,...

FiDUS Power is pleased to announce the addition of the exciting convection cooled, high efficiency, SUF350 AC-DC open frame power supply. With the SUF350, system designers can utilize 250W of output power from the dense 3 x 5” package without the need for fan cooling. Where fan...

FiDUS Power, the technical power supply distributor specializing in innovative solutions and new products that benefit system designers as they seek to differentiate their end products, sets a new bar for the size of external power supplies with the launch of the new model GDA200. The...
