It can be used in UPS systems, vending machines, medical devices and automotive components, among others. It also has a wide range of features such as adjustable current limit and dynamically variable frequency, which makes it suitable for a wide variety of applications.

The chip is extremely reliable, and its use in UPS systems can reduce the amount of circuit components and shrink the entire system size. It is also suitable for current limited power supplies, as it can be programmed with an adjustable current limit, allowing for higher efficiency and a smaller footprint. Furthermore, it is also advisable for medical applications due to their ability to work at a low current.

Working Principle

The LTC3785EUF-1#PBF operates by combining an Ultralow Dropout (LDO) regulator with a low current, frequency-controlled switch. The combined action inherently offloads the LDO regulator’s dropout voltage and results in higher efficiency compared to traditional voltage regulators.

The chip’s output voltage is controlled by varying the switching frequency. The chip has an internal oscillator and can be programmed to switch over a broad frequency range of 180 to 700kHz.

In addition to the variable frequency, the chip can also be programmed with an adjustable current limit that allows for higher efficiency and a smaller footprint in current limited power supplies.

The chip also features short-circuit protection, over-voltage protection, programmable soft start, and thermally-enhanced SOIC packaging.

Conclusion

The LTC3785EUF-1#PBF is a chip from the Variable Frequency Low Dropout (VF-LDO) family, which combines an Ultralow Dropout (LDO) regulator with a low current, frequency-controlled switch. It provides a reliable, high-efficiency, space-saving solution for various industrial applications, and its adjustable current limit, dynamically variable frequency and other features make it suitable for a wide variety of applications.
