DC DC converters are electronic devices that convert DC source power from one voltage level to another. The THN 20-4822WI is a DC DC converter that offers high efficiency and wide input and output ranges with active power management. This device is an ideal choice for applications in industrial, automotive, energy storage, communications, and consumer electronics.

The THN 20-4822WI is a highly efficient DC DC switching regulator that operates in a wide temperature range of -40° to +85°C. It provides adjustable output voltages of up to 48V and an input voltage range of 9 to 50V. This device improves efficiency using a BiCMOS fabrication process that enables the use of low-power components for reduced power dissipation and improved power efficiency. Its low power dissipation and small package size make it an ideal choice for space- limited applications.

The THN 20-4822WI offers constant frequency, current mode, voltage mode, and pulse-width modulation (PWM) with high drive capability to ensure superior control stability and transient performance. The device also features wide input voltage range and low-voltage shutdown to protect the system against reverse polarity and under-voltage conditions. In addition, it is designed with over-voltage protection and thermal shutdown to protect against short-circuit and other damaging conditions.

The THN 20-4822WI has a built-in analog programming feature to provide fast, convenient, and precise output voltage regulation. This feature can be programmed using a wide selection of programmable components, like resistors or potentiometers. The device can be used in single-ended or non-isolated topologies with both positive and negative output poles.

The THN 20-4822WI works on the principle of pulse-width modulation (PWM) which efficiently converts a DC input to a desired DC output. The internal PWM controller creates a rectangular waveform at a constant frequency, which acts as a carrier, and adjusts the duty cycle depending on the output voltage. This device features a fixed-frequency frequency modulation and a distortion-free linear modulation that ensures high efficiency, low ripple, and low EMI.

In summary, the THN 20-4822WI is a highly efficient DC DC converter designed for use in a variety of applications. It offers wide input and output voltage ranges, active power management, and protection from reverse polarity, under-voltage, over-voltage, and thermal shutdown conditions. The device also features adjustable output voltages, single-ended and non-isolated topologies, analog programming, and PWM with high drive capability. This makes the THN 20-4822WI an ideal choice for industrial, automotive, energy storage, communications, consumer electronics, and other applications that demand high performance and robust protection.
