The IC integrates the power MOSFET. With current mode control, ultra-low ESR capacitors, such as ceramic capacitors are used. The ICs have protection functions such as Overcurrent Protection (OCP), Undervoltage Lockout (UVLO), and Thermal Shutdown (TSD). An adjustable Soft-start by an external capacitor C4 prevents the excessive inrush current at start-up. The feature of increasing efficiency at light loads allows the project to be used in energy-saving applications. Due to the ICs integrating phase compensation circuit the number of external components count is low. Screw terminal provided for easy input and output connections. D2 Power LED indicates the output.
