DC DC Converters

DC-DC converters, also known as DC-DC power supplies, offer the benefit of providing a regulated DC output voltage from an unregulated DC input. The converter accomplishes this by taking energy from an input source, converting it into a different form, and then storing that energy into the form of a DC output voltage. The most common form of DC-DC converters is the linear regulator, which takes an AC input voltage and converts it to a regulated DC output voltage.

The R1DA-091515/P-R is a specified-performance DC-DC converter module from Artesyn Embedded Technologies. It is a non-isolated, two-step, soft-start, and step-up DC-DC converter (also referred to as a boost regulator), which has a wide-range nominal input voltage from 4.5 V to 30 V. The adjustable output voltage is available from 4.8 V to 15 V and the output current ranges from 0.45 A to 3 A. The R1DA-091515/P-R is designed for applications with stringent efficiency and noise requirements, such as industrial, medical, and communications. The system also has an extended temperature range from -40 °C to 85 °C.

Functional description

The R1DA-091515/P-R DC-DC converter module employs a two-step process for the conversion of input energy into a DC output voltage. First, the input voltage is regulated using the onboard control circuit. This sets the base reference voltage of the converter. The second step is then the conversion of this base reference into a DC output voltage. The output voltage is controlled by the closed-loop control circuit and a current-mode PWM (pulse-width modulation) converter, which accurately regulates the output voltage over the specified input and load range.

Application Field & Working Principle

The R1DA-091515/P-R is mainly used in power applications such as DC to DC converters, DC UPS systems, and DC-DC non-isolated bus converters. In these applications, the module provides a constant DC output voltage and current over the specified input load range. These outputs can be used to power other devices or components that require a regulated DC voltage.

The R1DA-091515/P-R operates in two-step process, first regulating the input voltage of the converter. The regulator uses a high-input voltage range and can accept an input voltage between 4.5 V and 30 V. The regulator also provides a fast response to load changes. The second step involves converting the regulated input voltage into a DC voltage. The voltage is regulated by the onboard current-mode control circuit and is accurately maintained over the specified input and load range.

The R1DA-091515/P-R has a unique feature of providing a soft start, which prevents it from in-rush current internally. This allows the module to slowly start up and increases system reliability. Additionally, the module also has a low standby current, which provides lower power consumption.
