PTH04T220WAS

DC-DC converters are electronic devices used to step-up, step-down, and invert the voltage of a DC source. The PTH04T220WAS is a DC-DC converter specifically designed for use in harsh environments. This device is suited for use in applications such as oil & gas, marine, and industrial equipment.

The PTH04T220WAS provides a fixed DC output voltage and is commonly used for isolated power supplies. It has a wide input voltage range of 8 to 36V, operating in either buck (step-down) or boost (step-up) mode. The device is also optimized to deliver maximum power and efficiency. It features a very low start-up current, which allows the device to start up faster. The PTH04T220WAS also features a thermal switch which tracks and regulates the temperature in order to avoid over-heating.

The PTH04T220WAS is rated for an output current of up to 220A and is designed with an EMI filter for EN55022 and FCC class B level performance. It also has robust protection features, such as over-voltage, over-current, and short-circuit protection. The device is also designed to withstand a wide temperature range with an operating temperature of -40 °C to +105 °C.

The PTH04T220WAS is a synchronous step-down DC-DC converter that employs a pulse-width modulation (PWM) control architecture. The device uses a voltage comparison circuit to generate a PWM signal that is used to switch power transistors. This modulated PWM signal is used to generate a stable output voltage while allowing for current-sharing during operation.

The device’s internal inductor further helps with voltage regulation. It stores energy during the charging phase, and then supplies the energy during the discharge phase. The internal inductor also helps to reduce the power losses associated with voltage regulation.

The PTH04T220WAS is an easy to use and robust device that is ideal for applications where reliable operation in harsh environments is a priority. The device has an adjustable switching frequency, and is designed to meet the requirements of EN 55022 and FCC class B standard.
