DC to DC converters, or DC DC converters, are circuit components that convert a voltage signal from one DC voltage level to another. This can be done using a transformer, resistors, or thyristors, but the most efficient method is using an integrated circuit, such as the RF700-48S28-5Y DC to DC converter. The RF700-48S28-5Y is a monolithic, high voltage DC-DC converter integrated circuit designed to provide the power to various applications requiring a high voltage from a low voltage power source, such as an industrial/commercial battery or similar battery.

The RF700-48S28-5Y is a step-up, boost-type DC-DC converter, meaning that it boosts the output voltage higher than the input voltage. It is capable of converting an input voltage ranging from 1.45V-14V to an output voltage of up to 48V. It has a wide input voltage range, low input current requirements, and high efficiency—up to 88%—making it an ideal power solution for applications where space, power efficiency, and cost are a factor.

The RF700-48S28-5Y has a wide range of applications. It can be used to power actuators, such as electric motors, for precise motor movement control, as well as for LED drivers, industrial displays, digital cameras, and HVAC control systems. The high switching frequency of the integrated circuit makes it ideal for driving inductive loads, such as stepper motors or audio amplifiers. It can also be used in automotive applications, such as in the headlamps and camera of an autonomous vehicle.

The RF700-48S28-5Y works by first rectifying the applied voltage using an internal power factor correcting (PFC) adjustable boost converter then applying the rectified voltage to an internal step-down voltage regulator to obtain the desired output voltage. The device features an adjustable output current limiting protection circuit to protect against overload. It also features a power-saving sleep mode that can be used to conserve power when the device is not in use.

The RF700-48S28-5Y is a robust, reliable, and cost-effective integrated circuit and is an ideal choice for a variety of high-voltage applications requiring an upconversion of voltage from a low voltage source. With its wide input voltage range, low input current requirements, high efficiency, and adjustable output current limiting protection, it is an excellent choice for automotive, industrial, and consumer applications.
