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 is a powerful yet small-size and low-profile brushed DC motor drive system, with key features like adjustable constant current control, direction control, brake controls, Alert output, PWM for speed control, etc. The BD63150AFM chip is the heart of the project which is one...

This over-current latch load switch provides over-current protection, thermal shutdown protection, soft-start function, and low power OFF function. The Overcurrent protection function is activated when the load is shorted. This protection function is effective in preventing damage due...

This Half-bridge module provides current measurement and regulation features for various loads. The module can be used to drive solenoids, Relays, Valves, DC-DC converters, Brushed DC motors, or other loads.  It can operate from a 5V to 55V supply voltage and can deliver up to 3A of...

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...

The project presented here is a dual 12-bit PWM-to-voltage output DAC with high accuracy. The board is based on the LTC2644 chip. The LTC2644 measures the period and pulse width of the PWM input signals and updates the voltage output DACs after each corresponding PWM input rising...

This Dual 2A Power Amplifier module is a low-cost operational amplifier designed for driving a wide variety of loads while operating on low-voltage supplies. The dual amplifier can drive high output loads with a current of up to 2A. This Dual 2A Power Amplifier has been designed as a...

The circuit shown here is a low-cost electronic DC load designed to sink current from a power source. This test equipment can be used to test power devices such as power supplies, chargers, solar panels, and batteries. The board is built using op-amp TLE2141, LM385 provides the...
