DC-DC converters are electrical devices which convert direct current (DC) from one voltage level to another, usually within the same type of DC source. The PAQ100S481R2/P is a highly efficient, isolated, offline, DC-DC converter in a compact, low-cost package. It features an integrated power MOSFET, optimised physical design and small size, making them ideal for use in space and weight-constrained applications such as those of medical and defence equipment.

The PAQ100S481R2/P offers a wide range of output voltages, making it suitable for a variety of applications from 3.3V to 50V. It has a wide input voltage range and operating temperature limits, allowing for a flexible use in various environments. With adjustable and selectable output current (I_MAX) of up to 7.5A, it meets the needs of many small to medium power requirements. The built-in MOSFET recirculation circuit allows the device to maintain a high efficiency even during high drain situations.

The working principle of the PAQ100S481R2/P is based on the buck-boost technique, in which the input voltage is switched to alternate between the output voltage and a higher or lower reference voltage. This causes the input voltage to be either stepped-up or stepped-down, thus providing the required output voltage. This is achieved by using an active control loop (PWM) to adjust the duty ratio of a pulse width modulation switch. The high frequency plus the built-in recirculation circuit allows the device to maintain a high efficiency even during light load operation.

As a DC-DC converter, the PAQ100S481R2/P can be used for a variety of applications, including medical equipment, defence equipment, extreme temperature operation, small and medium power requirements, and mixed signal applications. It is highly reliable and energy efficient, making it suitable for long-term use in critical applications.
