78SR110VC

DC-DC converters are used to convert one form of energy into another form in order to move energy between two nodes with different voltage levels. The 78SR110VC is a high performance, high voltage step-up DC-DC converter designed for applications ranging from 2V to 96V and up to 12A. It has an output voltage range of 2.5V to 150V and provides a high efficiency of >95%.The 78SR110VC utilizes an adaptive frequency modulation technique that optimizes the switching frequency between 350kHz and 780kHZ to improve efficiency and reduce EMI. It can operate in continuous conduction mode (CCM) and with pulse-sharing for easy paralleling and additional power scaling. The 78SR110VC also features internal soft-start, over voltage protection and thermal shutdown for enhanced safety and protection.The principle that makes the 78SR110VC work is known as voltage step-up conversion. This type of conversion uses two voltage sources, one lower than the other, to create a higher voltage level. In the 78SR110VC, the lower voltage source is the input voltage, typically ranging from 2V to 96V, and the higher voltage source is the output voltage, typically ranging from 2.5V to 150V.The 78SR110VC uses the adaptive frequency modulation technique to reach its high levels of efficiency, as it works to reduce the loss and minimize input ripple. The internal switch mode control modifies the switching frequency based on input and output voltage and current conditions. An external clock can be used to set the highest switching frequency which allows the system to reach more than 95% efficiency. The integrated soft-start feature helps to reduce startup losses as well as in-rush current. During start-up, the internal controller gradually increases the switching frequency from 0kHz to the predetermined frequency, allowing the system to gradually increase the output voltage until it reaches the desired output voltage. Additionally, the voltage protection feature is triggered when the output voltage is outside of the preset ranges for a period of time, preventing damage to the system.The 78SR110VC is a high-performance, high-voltage DC-DC converter designed for applications ranging from 2V to 96V and up to 12A. It has a wide output voltage range of 2.5V to 150V, and can reach efficiencies of up to 95%. Additionally, it features an adaptive frequency modulation technique that optimizes the switching frequency between 350kHz and 780kHZ to improve its efficiency, as well as a soft-start, over voltage protection, and thermal shutdown for enhanced safety and protection.
