A DC DC converter is a device that converts DC power from one voltage level to another. It is an electronic power converter that takes DC from one voltage source, e.g. a battery, and outputs DC at another voltage. The A20P-12 is a DC-DC 18-75V input voltage range, 12V/20A (240 watts) point-of-load (PoL) personal computer power supply, occupying only a 0.85" x 1.90" footprint.

The A20P-12 operates as a non-isolated step-down fixed-input DC DC converter. Its input voltage range comprises both single-ended and differential input signals between 18V and 75V, enabling a wide range of power challenges to be solved with a single product. Its 12V/20A output is able to supply up to 240 watts power, suitable for a range of applications.

The A20P-12 offers a number of features that make it well-suited for many types of personal computer power supplies, especially those in markets such as automotive, test and measurement, industrial, military, and telecommunications. These features include wide input voltage range, low and full-range remote power sensing, integrated EMI filters, primary and secondary over-current protection, active over-temperature protection, and 98%-efficiency. All these features provides the user with the necessary confidence in its performance in various applications.

The A20P-12 operates on a fixed-input DC-DC converter topology, providing a high-efficiency conversion from input voltage levels of 18V to 90V down to constant output voltage levels of 12V. The device is integrated with an EMI filter to reduce external noise contribution and the possibility of interference with other devices. In addition, the A20P-12 offers low to full-range remote sensing capability, permitting fine-tuning of the output voltage and maximizing the efficiency of the overall system.

The A20P-12 includes an over-current protection (OCP) circuit designed to detect and protect the device from excessive load current. This OCP circuit monitors both the primary and secondary sides, and adjusts the load current to the maximum current rating of 20A (240 watts). The device also includes a temperature protective circuit that monitors the temperature within the device and shuts off the output when the temperature exceeds its rated operating limit.

The A20P-12 is an ideal DC-DC converter for applications that require high power outputs, integrated protection, and low output noise. It is well-suited for many personal computer related applications such as automotive, test and measurement, industrial, military, and telecommunications. Its 18-75V input voltage range makes it a versatile solution for many different power challenges and its 98% efficiency makes it a cost effective choice.
