DC-DC converters require energy conversion from one DC voltage to another. The ZTS34812 DC-DC converter is an on-board voltage converter product that provides an efficient and cost effective solution to these applications. In this article, we will discuss the application field and working principle of the ZTS34812 DC-DC converter.

Application Field

The ZTS34812 DC to DC converter is designed for use in scenarios where it is important to convert a higher input voltage to a lower output voltage. This is suitable for applications such as automotive systems, telecoms systems, instrumentation, and industrial applications. The converter is rated to 22 Amps and can handle up to 100 Watts. It can accept input voltages in the range of 10.8V to 60V, and can output voltages ranging from 4.5V to 18V. The converter features a wide temperature range of -40 to 125°C and has an extreme high efficiency of 90% to 95%.

Working Principle

The ZTS34812 DC to DC converter works in full-range voltage conversion mode. Its working principle is based on two switches that are connected in series to the input voltage, and a pair of inductors that form a series circuit. The switches are driven by a control circuit, and the output voltage is regulated by an error amplifier circuit. The converter operates in a buck-boost switching mode, allowing it to accept a wide input voltage range and output a stable output voltage. The converter features over-voltage protection and over-current protection, and also features soft start protection.

The input and output current ripple is kept very low, and the converter runs in a synchronous mode with a fixed frequency, which helps reduce switching losses. When the output voltage drops below a certain point, the converter automatically switches to a discrete mode, where the voltage is regulated by controlling the duty cycle. This enables the converter to maintain the output voltage with minimal power loss.

The ZTS34812 DC to DC converter has a wide range of applications due to its high efficiency and excellent performance. It is suitable for a variety of different applications, from automotive systems, telecoms systems, instrumentation, and industrial applications. Its ability to support high input voltage and output voltage, and to maintain steady voltage regulation, make it an ideal choice for applications that require efficient energy conversion.
