LT3471EDD

The LT3471EDD is a high-efficiency, low-noise step-down DC-DC converter manufactured by Linear Technology (now part of Analog Devices). It operates over an input voltage range of 2.25V to 16V and can deliver up to 1A of output current. The device utilizes a constant frequency, current mode architecture to provide fast transient response and stable operation across a wide range of load conditions. Its integrated low RDS(ON) N-channel switch ensures high efficiency operation. The LT3471EDD offers adjustable output voltage via an external resistor divider and features a fixed frequency oscillator, programmable soft-start, and thermal shutdown protection. The device is housed in a 10-lead DFN package, making it suitable for compact designs in various applications such as industrial, automotive, and portable electronics. Its versatile features and compact form factor make it an ideal choice for power supply designs where efficiency, flexibility, and reliability are crucial
