ROL-1215S/H belongs to DC DC converters, and is widely used to convert DC power to AC power or another different DC power. It has the capability to output safety isolated DC power sources and is used in applications such as motor control, automotive navigation systems, video surveillance, medical imaging devices, and telecom gateways.

The ROL-1215S/H is a high-voltage, low-current, high frequency, Dc-to-Dc converters that serve as power line receivers. It has an adjustable output voltage and current control range that can be programmed. This is done through programming pins and is adjustable through the onboard display. It also includes an over-voltage protection circuit, over-current protection circuit, and over-temperature protection circuit for safety.

The working principle for the ROL-1215S/H converter is based on a single-ended primary inductor converter (SEPIC) topology. In the SEPIC converter, a single inductor is used to provide both isolation and voltage conversion. In the ROL-1215S/H, the input voltage is applied across the inductor, and the current is regulated using an external controlling switch. The control switch is used to dynamically control the output voltage. The output voltage is determined by the voltage across the inductor divided by the number of turns of the inductor.

In order to produce an adjustable DC power output, the internal converter is equipped with an analog-to-digital converter that is used to regulate the switch. The analog-to-digital converter is then used to control the duty cycle of the switch, which in turn is used to vary the output voltage. The analog-to-digital converter also provides feedback to the control circuit which is used to maintain a constant output voltage.

In addition to the analog-to-digital converter, the internal converter is also equipped with a feedback-controlled voltage regulator that adjusts the output voltage according to the external load. This allows the ROL-1215S/H to adjust the output voltage to meet the external load requirements, while still maintaining a high voltage conversion efficiency.

In conclusion, the ROL-1215S/H is a DC-to-DC converter that is used to convert DC power to AC power or another different DC power source. It has the capabilities to output safety isolated DC power sources and is used in various applications such as motor control, automotive navigation systems, video surveillance, medical imaging devices, and telecom gateways. The working principle for the ROL-1215S/H converter is based on a single-ended primary inductor converter (SEPIC) topology. This provides the capability for the internal converter to adjust the output voltage based on the external load requirements, while still providing a high voltage conversion efficiency.
