The LTC3879EMSE#PBF is a high-performance, synchronous step-up DC/DC controller from Analog Devices. The device can generate output voltages up to 80V with a 350kHz switching frequency and is suitable for applications like DC/DC converters, LED lighting, LED displays, and motor controllers. It features hot-swap capabilities, allowing the converter to start up even when its input voltage is below the set point. The LTC3879EMSE#PBF is protected from over-voltage, over-current, and open-wire faults, providing reliable operation. Additionally, it can support programmable switching frequencies, allowing for efficient designs with custom noise and EMI filtering requirements.
