This is a versatile synchronous buck DC/DC converter built using the LM5008 chip. The operating input voltage range is 12V to 95V DC, providing 5V/120-350mA output. The regulator can provide a load current of up to 350mA, but it's advisable to draw only 120mA due to the small thermal...

This is a versatile synchronous Buck DC/DC converter built using the LM5007 chip. It operates with an input voltage range 12V to 75VDC, and provides 10V/250mA output. The regulator can provide load current up to 400mA, but it is advisable to draw only 250mA due to the small thermal...

This is a DC/DC converter that combines a traditional voltage feedback loop and a unique current feedback loop to operate as a constant-current, constant-voltage source. The project has been designed using the LT1618 chip. The board provides 12V/150mA output, from input supply 1.8V to...

This Phase-shifted Full-Bridge controller with synchronous rectification carrier board contains all of the features necessary to implement a phase-shifted full-bridge with a synchronous rectification topology power converter. All inputs and output pins are accessible using a header...

This simple, compact solution is ideal for isolated SPI data requiring communication across different ground potentials often found in Industrial PLCs (programmable logic controllers) and Instrumentation and data acquisition systems. Serial Peripheral Interface (SPI) is a protocol...

The project presented here is a galvanically isolated differential line transceiver with a built-in isolated DC-DC converter for TIA/EIA RS-485 and RS-422 applications. Both signal and power paths are isolated per UL1577 and are qualified for reinforced isolation per VDE, CSA, and...

This is a low-cost boost converter that converts a 3.3V input to 5V at 250mA load current. The LM2578A chip is used to build this project. The LM2578A is a switching regulator which can easily be set up for such DC-to-DC voltage conversion circuits as the buck, boost and inverting...

This high-performance, fixed frequency, current-mode PWM step-up DC/DC converter efficiently produces 12V from input voltages between 3.6V to 5.5V. The project is built using the PAM2423 chip, which includes an integrated power MOSFET that supports a peak current of up to 5.5A.  The...
