ISD0105D05 Power Supplies - Board Mount

DC-DC converters are electronic devices used to convert direct current (DC) from one voltage level to another. The ISD0105D05 is an adjustable single-input and single-output DC-DC converter. It offers high-efficiency operation, high accuracy, and an extremely wide input voltage range. Many applications require a DC-DC converter to run efficiently. It is thus important to understand the working principles and fields of application of the ISD0105D05.

Input Voltage Range

The ISD0105D05 operates on a wide input voltage range of 6.7 V to 48 V. It provides a regulated output voltage range of 0.7 V to 15 V and can deliver a continuous power up to 10 W. Its switching frequency can be adjusted in increments from 100 kHz to 600 kHz. It is highly efficient and maintains load and line regulation performance over a wide input voltage range.

Output Voltage Regulation

The ISD0105D05 incorporates a voltage-mode buck-boost topology that uses an N-channel MOSFET as a main switch. When the MOSFET is switched off, energy is stored in the input capacitor. The main switch also controls the current flow, enabling the output voltage to be varied. This regulator has an integrated soft-start function and allows the output voltage to be adjusted with an external resistor.

Protection Features

The ISD0105D05 offers various protection features, such as over-temperature protection, over-current protection, and short-circuit protection. It also provides an under-voltage lockout (UVLO) to protect the system from built-in voltage spikes. An enable signal sequences the device on and off, allowing the converter to be safely shut down and for the output voltage to be temporarily adjusted.

Application Fields

The ISD0105D05 is suitable for a wide range of applications, including industrial systems, medical equipment, consumer electronics, automotive applications, and solar energy systems. Its wide input voltage range and adjustable output voltage capability make it an ideal solution for applications where efficient power conversion is required. Additionally, the integrated safety features make it an ideal solution for mission critical applications such as medical electronic equipment and automotive systems.

Conclusion

The ISD0105D05 is a highly versatile DC-DC converter that provides high efficiency and high accuracy over a wide input voltage range. It has a wide adjustable output voltage range, providing an ideal solution for a variety of applications. Additionally, its protection features make it an ideal choice for mission critical applications. The ISD0105D05 is a reliable and efficient device that makes power conversion tasks easier and more reliable.
