PH75F110-3

Ph75F110-3 Application Field and Working Principle

The Ph75F110-3 is a point of load DC/DC converter with an integrated controller for voltage and current conversion. It is a high-efficiency and highly-flexible solution for applications requiring a wide input voltage range and low output power ratings. It is designed for applications such as data acquisition, communication systems, power supplies, and precision instrumentation.

The operating principle of the Ph75F110-3 is based on a P-channel MOSFET being used as a switch, in conjunction with a current-mode switching controller, to regulate the output voltage. When the voltage is low, the P-channel MOSFET is turned on to increase the load current, which increases the output voltage. The current-mode controller then senses the output voltage and turns off the MOSFET when the desired voltage is reached. The output voltage is kept constant by a feedback loop that continuously monitors the output voltage and adjusts the P-channel MOSFET accordingly.

The wide input voltage range allows the converter to work in a wide variety of applications. Its efficiency is high compared to other comparable DC/DC converters, with no need for active cooling systems. In addition, the Ph75F110-3 is a highly reliable device, as it is tested under extreme conditions and meets high standards for surge, transient, and EMI suppression.

The Ph75F110-3 has a built-in overvoltage and overcurrent protection and an adjustable overvoltage protection level. This allows for precise voltage and current control, while preventing potential damage to the components. In addition, the converter features an internal power switch for current rating monitoring. This allows for safe operation and easy system integration.

The Ph75F110-3 is a versatile, high-efficiency DC/DC converter capable of providing a wide range of output voltages, currents, and power levels for a variety of applications. Its wide voltage range, current over limit protection, and built-in power switch make it an ideal solution for a variety of industrial and commercial applications.
