LT8705EUHF

The LT8705EUHF is an advanced high voltage synchronous buck-boost controller that allows for a wide range of input and output voltage. By using two mosfets, the LT8705EUHF controller can reduce the size and cost of the power supply, since it takes up less board alternate space. The two mosfets also enable the LT8705EUHF to provide adjustable voltage with wide current range.

The LT8705EUHF is suited for a range of application fields. It can be used for step-up or step-down voltage conversion, such as DC-DC converters and point of load (POL) converters. It is also capable of powering off-board applications, such as off-battery charging and motor control. The LT8705EUHF is also suitable for a variety of industrial applications such as light dimming, LED drivers, and other industrial automation.

The working principle of the LT8705EUHF is based on a synchronous rectified buck-boost scheme. The controller enables the output voltage to be adjusted by setting the duty cycle of the two external power MOSFETs. The duty cycle of the two switches is determined by two digital controls: one for the boost MOSFET and one for the buck MOSFET. This allows the LT8705EUHF to operate over a wide output voltage range, with adjustable power and current.

The LT8705EUHF has a number of features to ensure efficient and reliable operation. For example, it features wide synchronous frequency range and ability to work in both step-up and step-down modes. It also has internal soft start, over temperature and over-current protection, and fast response and loop compensation. These features ensure the LT8705EUHF works reliably and efficiently in a wide variety of applications.

In summary, the LT8705EUHF is an advanced synchronous buck-boost voltage regulator that is suitable for a wide range of applications. It is capable of providing adjustable voltage with wide current range and features a range of features to ensure reliable and efficient operation. This makes the LT8705EUHF an ideal choice for powering off-board applications, such as off-battery charging and motor control and for a variety of industrial applications such as light dimming and LED drivers.
