The LTC3872EDDB#PBF is an integrated synchronous flyback controller and synchronous buck regulator by Analog Devices. It is designed to provide an isolated ultra-low noise 5V/3A output and a 5V/3A synchronous buck output, both with fast transient response. It features a pin-programmable average current-mode architecture with a wide range of output voltages, high current capabilities, and many protection features, and is ideal for telecom, networking and datacenter power supplies. The device features 0.5% current accuracy, 5,000:1 peak-current-mode control, programmable soft-start, output overvoltage and overcurrent protection, an enable input, and output voltage tracking.
