DC DC converters are electronic devices that convert energy from one form to another, usually from one DC voltage to a different, higher or lower, DC voltage. DC-DC converters are used in a variety of applications that require reliable conversion, including power handling, communications, medical equipment, and much more. The REC3-243.3SRWZ/H2/A/SMD/CTRL is one of these DC-DC converters. This device is designed to provide an efficient and reliable DC-DC conversion solution for all types of applications.

The REC3-243.3SRWZ/H2/A/SMD/CTRL is a non-isolated, current mode, single-ended primary-inductor converter. It operates with a wide input voltage range from 3.3V to 36V, and delivers a programmable output voltage of up to 35V. The output voltage can be configured via external resistors or digitally programmed via I2C. The device features excellent transient response characteristics, protected overload, and over-temperature conditions. It also includes comprehensive diagnostics and protection features to ensure longevity and reliability.

When it comes to the application field of the REC3-243.3SRWZ/H2/A/SMD/CTRL, this DC-DC converter is suitable for many different applications. It can be used in industrial, medical, automotive, and consumer applications that require efficient DC-DC conversion. Examples of such applications include portable systems, measuring equipment, PC motherboards, software-defined radio communication systems, and more.

The working principle of the REC3-243.3SRWZ/H2/A/SMD/CTRL is based on the PWM control concept. In this controller, a voltage sensor is used to detect the input voltage. The PWM controller then adjusts the switching duty cycle to maintain the output voltage. The primary side of the converter uses a power MOSFET and an inductor to store and transfer energy. The secondary side uses a power MOSFET to transfer the stored energy to the output. The output voltage is regulated by the peak current control method.

When the input voltage falls below the preset voltage level, the power MOSFET on the primary side of the converter is turned on and will start to conduct current. The current from the input will pass through the inductor, and the inductor is designed to store energy in a magnetic field. As the voltage across the inductor increases, the power MOSFET on the primary side start to decrease its switch frequency and enters a valley switching mode. At this moment, the energy stored in the inductor will be transferred to the output by the power MOSFET on the secondary side. The output voltage can be APD regulator or digitally programmed through I2C.

The REC3-243.3SRWZ/H2/A/SMD/CTRL is a high-efficiency, low-noise, and low-EMI DC-DC converter. It is a reliable and cost-effective solution for a wide range of applications. Its excellent transient response, comprehensive diagnostics and protections make it a great choice for applications that require efficient and reliable DC-DC conversion.
