REC7.5-1205SRW/H2/A/M/SMD/CTRL-R

DC-DC converters are commonplace devices used for the purpose of transforming direct current (DC) from one voltage level to another. They are frequently used to provide power to a component or system where the available DC source is of a different voltage than the required level. An example of a DC-DC converter is REC7.5-1205SRW/H2/A/M/SMD/CTRL-R, a non-isolated synchronous buck (step-down) converter.

This converter can convert an input voltage of between 6.5 V and 13.2 V into an output voltage of 0.8 V to 10.8 V. Its features include 2 A continuous output current, ±2% initial accuracy, ultra-fast transient response, high efficiency of up to 92%, and high switching frequency up to 1.5 MHz. It also benefits from excellent line and load regulation, as well as current, thermal, and short-circuit protection.

The REC7.5-1205SRW/H2/A/M/SMD/CTRL-R has a wide range of applications, including distributed power systems, base station power supplies, and point-of-load converters. It can be used in a variety of industrial applications, such as medical equipment, instrumentation, cars, and other automotive applications.

The working principle of the REC7.5-1205SRW/H2/A/M/SMD/CTRL-R is based on the standard pulse width modulation (PWM) synchronous buck converter structure which consists of an inductor, two switches, two diodes, two capacitors, and the remaining passive components. When the switch is turned on, energy is stored by the inductor in the form of magnetic flux. When the switch is turned off, the energy stored in the inductor is released by the diode to the output capacitor which adjusts the output voltage.

The two switches are driven by a PWM signal from the control IC, and the ON time of the switches is determined by the duty ratio of the PWM signal. This PWM signal is generated according to the comparator output which compares the feedback voltage with an internal reference voltage. When the feedback voltage is higher than the reference voltage, the comparator output is high, and vice versa.

The REC7.5-1205SRW/H2/A/M/SMD/CTRL-R is a high-efficiency, cost-effective DC-DC converter with a wide input voltage range and many features. It has a wide range of applications and is suitable for all industrial and automotive systems. Its working principle is based on the standard PWM synchronous buck structure, making it a reliable and easily implementable solution.
