The LTC3780IG is a high-performance, synchronous buck-boost DC/DC converter controller from Analog Devices. It can seamlessly regulate the output voltage, even when the input voltage is above, below, or equal to the output. This versatility makes it ideal for battery-powered applications or systems with widely varying input supplies. The LTC3780IG offers high efficiency (up to 98%) by utilizing synchronous rectification, and it supports output voltages ranging from 0.8V to 30V. Key features include current-mode control, programmable soft-start,LTC3780IG overcurrent protection, and excellent line/load transient response. It operates over a wide temperature range, making it suitable for industrial, automotive, and telecommunication applications.
