DC-DC converters have been an important part of electronics for decades. They are used in many applications ranging from powering small our toys to providing power in automotive and industrial applications. The RW2-4809D/H2 is one such DC-DC converter. This converter is commonly used in power supply applications in which it provides a constant regulated output voltage regardless of input variations.

The RW2-4809D/H2 is a non-isolated step-down DC-DC converter. This means that the input voltage is directly connected to the output with no isolation between them. This reduces the complexity of the circuit as well as the cost.

The RW2-4809D/H2 provides a constant output voltage of 24V. It can take an input voltage of 8-36V and provide an adjustable output of 24V (24.5V max) with a range of 1-100%. The output voltage is controlled by the duty cycle of the PWM signal on the reference pin, meaning the converter can be adjusted using either a logic level signal or an external potentiometer. The maximum output current is 9A, with a rated output voltage of 1% and temperature coefficient of 25mV/°C.

The RW2-4809D/H2 is designed to operate over a wide temperature range. It can operate at junction temperatures of -55°C to +125°C, and can survive temperatures up to +135°C. It also has over temperature, over current, and over voltage protection mechanisms built in to protect the converter from damage in the event of a fault.

When designing a circuit with the RW2-4809D/H2 DC-DC converter, it is important to take into account certain parameters such as the input and output capacitance, the voltage and current rating, the power dissipation, and the operating frequency. The converter should also be mounted onto a heatsink to ensure the heat generated is dissipated effectively.

When it comes to its application, the RW2-4809D/H2 is ideal for powering applications such as medical equipment, industrial and instrumentation equipment, and driving motor control systems. It is also a suitable choice for automotive, aerospace, and military applications. With its wide input and output voltage range, high efficiency, and accurate output regulation, the RW2-4809D/H2 is a reliable choice for powering electronic systems.
