DC-DC converters are electrical components that act as an interface between different energy sources. In order to generate a voltage suitable for a particular use, a device commonly referred to as a DC-DC converter is employed. The DC-DC converter functions to transform low-voltage DC input sources to high-voltage levels for use in a range of applications. As well as enabling the transfer of power from a low voltage to a high voltage, an efficient DC-DC converter allows high power transmission with minimal losses.

One specific type of DC-DC converter is the RTS-1515/P. This device is a versatile, high-efficiency switch-mode DC-DC converter able to convert regulated AC or DC inputs into selectable 115Vrms or 230Vrms isolated outputs with the dedicated output voltage select switch. The wide 4:1 input range of RTS-1515/P makes it suitable for many applications. As the RTS-1515/P has a regulated output voltage, it is able to operate in a wide supply voltage range and the output is free from interference from power line noise.

Applications for RTS-1515/P mainly involve the powering of high-power LED lighting or LCD panels, but it is also suitable for powering a range of audio systems. They are used where higher power and current requirements, but lower power and voltage requirements, are needed. This makes them an ideal choice for powering LCDs and LED displays in a range of industrial applications and for supplying backlighting in a variety of applications. The device also has other applications including powering up a medical device, POS terminal, small automotive components, and so on.

Working Principle of RTS-1515/P

At the heart of the RTS-1515/P is a synchronous rectifier and an AC/DC converter. The AC/DC converter works on the principle of pulse width modulation (PWM) to regulate the output voltage. During in the operating process, a frequency-controlled oscillator generates a PWM counter signal. The duty cycle of the PWM signal is modulated according to the output voltage. Thus by controlling the duty ratio of the PWM signal, the output voltage is regulated to the desired level.

The RTS-1515/P is also designed to monitor the output current with a current sense circuit and secondary side rectifier circuit. This allows the controller to detect the output current and limit it within its rated current. This helps to avoid any over-current conditions and increases the life of the converter. The output current is also maintained at the desired level and the output voltage is kept stable under dynamic load conditions.

The synchronous rectifier circuit is also responsible for providing a low output impedance and faster transient response, which has enabled RTS-1515/P to achieve high efficiency.

In summary, the RTS-1515/P is a versatile DC-DC converter capable of converting regulated AC and DC inputs into selectable 115Vrms or 230Vrms isolated outputs. It is used to power a range of electronic display panels, including LCD and LED displays, and can also be used in industrial, medical, automotive and POS applications. Its efficient design has enabled it to operate in a wide supply voltage range and with minimal power losses. Its ability to maintain the output current and voltage under dynamic load conditions and its fast transient response has enabled it to achieve high efficiency.
