A12P-5

DC-DC converters are widely used for electrical power conversion. A12P-5, a DC-DC converter, is designed to regulate and convert voltage and current from one DC voltage source to another DC voltage source. It is specifically designed for low-power applications with high efficiency, tight line/load regulation, and low output noise.

Overview of A12P-5

The A12P-5 is a non-isolated, “buck” type DC-DC converter that takes input voltage from 4.5V to 30V to generate an adjustable output voltage of 0.6V to 15V at up to 5A. It has a synchronous rectified topology that provides up to 90% efficiency across all load currents. It is rated for operation in a temperature range from -40 degrees Celsius to 85 degrees Celsius. Its small size (1.25” x 0.9” x 0.32”) and light weight (less than 1 ounce) make it ideal for small and portable applications.

A12P-5 Application Field

The A12P-5 can be used for a variety of applications, including portable medical devices, robotic control systems, small automotive applications, and home-automation systems. With its small size and light weight, it is ideal for use in battery-powered, portable devices such as cell phones and portable video cameras. Its efficient operation and low minimum-output voltage of 0.6v make it well suited for point-of-load applications in complex electronic circuits.

A12P-5 Working Principle

The A12P-5 is a synchronous buck converter, which means that it uses a switching power stage to regulate the output voltage. It has an internal MOSFET switch, as well as an external control circuit, which enable the device to regulate the output voltage. The external control circuit uses a Pulse Width Modulation (PWM) technique to regulate the output voltage. The external circuit controls the duty cycle of the PWM signal, which adjusts the on-time of the switching power stage. When the duty cycle is increased,the switching cycle is shortened and the output voltage is lowered. Conversely, when the duty cycle is decreased, the switching cycle is extended and the output voltage is raised.

The A12P-5 also has current-limit protection. When the output current reaches its limit, the voltage regulator will turn off the internal MOSFET switch, limiting the output current to the rated value. This feature helps protect the device and system components from excessive currents.

Conclusion

The A12P-5 is a robust, relatively small, and efficient DC-DC converter designed to provide adjustable output voltages from 4.5V to 30V. Its small size and light weight make it an ideal choice for portable applications, while its tight line/load regulation and low output noise make it suitable for a variety of complex circuits. Furthermore, its current-limit protection makes it a very reliable device, providing protection from excessive currents.
