DC-DC Converters

DC-DC converters are electric devices that convert a dc power source into a dc power output with different values. DC-DC converters can be used in a variety of applications, including automotive, industrial, and agriculture.

TEL 15-1222 Application Field and Working Principle

The TEL 15-1222 is an isolated dc-dc converter. It is designed to provide a regulated and isolated input voltage to high-performance electronic systems. With its wide input voltage range of 4.5V to 48V and output voltage range of 1.2V to 39V, it is suitable for various applications, including industrial and automotive.

The TEL 15-1222 can deliver up to 3A of continuous current and 5A of peak current. It is available in a compact 12-pin DIP package and includes an external enable pin for easy integration and control. Furthermore, it provides excellent voltage accuracy and temperature stability for optimum performance.

The TEL 15-1222 utilizes two principle techniques to achieve high efficiency: discontinuous conduction mode and pulse-width modulation. Discontinuous conduction mode is used to regulate the output voltage by dynamically varying the amount of time the inductor is engaged. Pulse-width modulation is used to convert input over a wide voltage range with high efficiency by regulating the switching frequency.

The TEL 15-1222 also provides excellent EMI protection. It is equipped with a low-noise, synchronous rectifying switcher, an integrated EMI filter, and an external enable pin for easy integration and control. It has a wide range of operating frequency, from 75kHz to 1MHz, and can be easily configured with external components such as capacitors, inductors, and resistors.

The TEL 15-1222 is an efficient and reliable DC-DC converter designed to provide an isolated and regulated input voltage to various applications. With its wide input voltage range, high conversion efficiency, and excellent EMI protection, it is an ideal solution for temperature controlled applications such as industrial and automotive.
