The power board described here is designed for motor applications, featuring the 6ED2230S12T gate driver IC and FP15R12W1T4 IPM power module from Infineon. It provides an AC input and a 3-phase power output, with a single emitter shunt for current sensing and a voltage divider for...

A simple photovoltaic (PV) to Li-On battery charger project is described here. At low VCC voltage, PV current flows to both the system at VCC and the battery. When VCC reaches the programmed float voltage (4.1V with ADJ floating), the LTC4071 shunts excess current not used by the...

This is a 2Vrms Pop-Free stereo line driver with a stereo headphone driver designed to allow the removal of the output DC-blocking capacitors for reduced component count and cost. The project is based on the DRV604 chip which is ideal for single supply electronics where size and cost...

This is a Dual Mode regulator intended for Automotive, battery-connected applications that operate with up to a 36V input supply. Depending on the output load, it operates either as a PWM Buck Converter or as a Low Drop-Out Linear Regulator, and is suitable for systems with low noise...

This is a breakout board for the IC PCM1795 stereo digital-to-analog converter (DAC), The DAC module accepts pulse code modulation (PCM) and direct stream digital (DSD) audio data formats, thus providing an easy interface to audio digital signal processors (DSPs) and decoder chips...

This is a fantastic project for makers, offering multiple output options of 3.3V, 5V, and 12V, with an input of 18-24V DC. This project is built around the MP2451 high-frequency (2Mhz) step-down switching regulator, ensuring efficient and reliable power conversion. For added...

This board is built using a 2 x INA149 precision unity-gain difference amplifier with a very high input common-mode voltage range. The project can be used as a current sensor for high-voltage applications, INA149 provides a common-mode voltage range of +/-275V. The project operates...

This low-side voltage-to-current (V-I) converter delivers a well-regulated current to a load. The circuit accepts an input voltage from 0V to 3V and converts it to a current from 0A to 6A (combined). The current is accurately regulated by feeding back the voltage drop across a...
