The PTMA403033A1AZ is a high power DC-DC converter with an input voltage range of 9 to 36V DC, and an output voltage of 3.3V/2A. It has an efficiency of up to 97.5%, an operating temperature range of -55°C to +85°C, and a high power density of 12.6W/cm3, which is ideal for high efficiency and low noise solutions.

This product is designed for extreme environments, and is capable of supporting a wide range of applications including aerospace, defense, and power generation. It is also certified for safety according to several international standards, including EN 55022 Class B and EN/UL60950-1. This ensures that the PTMA403033A1AZ meets the most stringent requirements when used in demanding conditions.

In terms of working principle, the PTMA403033A1AZ is a switch-mode power supply that converts an input voltage into a controlled output voltage. It consists of two main components, a switching device and an inductor. The switching device, usually a transistor or a switch, is controlled by an internal controller. This controller switches the transistor or switch at a specific frequency, allowing energy to be transferred from the input to the output at an efficiency of up to 97.5%. The inductor, which is also known as the "converter element", stores the energy in a magnetic field, and then releases it to the output once the transistor or switch is turned off.

The PTMA403033A1AZ offers stable, reliable, and sufficiently filtered low and high power outputs, with minimal EMI and no droop or cross regulation. It is designed to meet the strict requirements of space-grade applications, and is a robust, reliable power solution for extreme environments. This product is easy to integrate and install, making it a great choice for applications in the aerospace, defense, and power generation fields.
