DC-DC converters are power electronic systems used to transform an input direct current supply to an output direct current supply with a well-defined voltage, current, and power. The type of DC-DC converter which is the focus of this discussion is the R1Z-1505/H, a 10 watt non-isolated DC-DC module. This type of converter is used to provide power to small electronic systems such as in mobile phones, portable CD players and other intricately designed electronic appliances.

Applications

The R1Z-1505/H is designed merely for the use of low-power applications, primarily in SMPS (Switched Mode Power Supplies). The power output of the R1Z-1505/H is 10W and its operating temperature is -40°C to 85°C. This DC-DC converter works within a 5 to 36V range and can provide an output voltage from 0.8V to 5V with an accuracy of ±2%.

Being an efficient and reliable small module, the R1Z-1505/H converter has laser trimmed components integrated in the system to enable the strict control of adjustments by compensating parameters such as ripple, input/ output isolation, and internal insulation. The converter can therefore meet the technical requirements for input voltage, output current, temperature coefficient, inrush current, and efficiency.

Overall, the precise design of the R1Z-1505/H DC-DC converter makes it suitable for a variety of applications such as medical, industrial, communications, aerospace, and automotive systems. Such systems typically require the provision of regulated power with small size and low output noise.

Working Principle

The working mechanism of a R1Z-1505/H DC-DC converter is essentially the same as most other converters. As the name suggests, the converter works to convert direct current from one voltage level to another. To achieve this, the DC-DC converter incorporates a voltage booster, voltage regulator and a control circuit in the form of one integrated module.

The voltage booster consists of an inductor (L1) and a capacitor (C1) connected in series, while the voltage regulator is in charge of the electrical output. Both of these components together form a voltage conversion loop and are known as a non-isolated step-up type module.

The voltage booster works by collecting a source voltage from the input port and then converting it into a high output voltage. The capacitor C1 acts as a temporary storage device, which stabilizes the output voltage. Meanwhile, the inductor L1 increases the voltage and enables the power to be stored in the capacitor C1, which releases it later to the output port. The voltage regulator, on the other hand, is responsible for controlling the output voltage and current.

The R1Z-1505/H DC-DC converter also has a control circuit, which reduces the power consumption of the entire system. The control circuit helps to maintain the voltage conversion loop and provides precise control over the output voltage, current, and power. It also serves to stabilize the system and ensure that the output voltage does not drop or surge during normal operation.

In summary, the R1Z-1505/H DC-DC converter is mainly used for low power applications, with an operating temperature of -40°C to 85°C, an input voltage within the range of 5 to 36V and an output voltage accuracy of ±2%. The working mechanism of the converter is essentially the same as any other DC-DC converter. It comprises a voltage booster, a voltage regulator, and a control circuit, all of which enable the device to deliver a regulated output voltage and current without the need for external circuitry.
