LTC3441EDE#TRPBF is a synchronous buck DC/DC switching regulator controller. It is mainly used in point-of-load (PoL) DC/DC converters and provides a complete, efficient and feature-rich design solution. It is specifically designed to convert a higher input voltage to a lower output voltage. The part is labeled “EDE,” indicating its wide 3V to 18V input voltage range and its ability to deliver up to 8.0A of continuous current at the output.The LTC3441EDE#TRPBF is a synchronous buck switching regulator that provides a complete solution for building a wide variety of DC/DC converters. It utilizes a voltage mode architecture to provide fast transient performance, excellent line and load regulation, and over-current protection through the use of peak-current-mode control. When enabled, the LTC3441 refreshes the output on every cycle and does not require an external compensation capacitor, making it ideal for a variety of power applications.At the heart of the LTC3441EDE#TRPBF is a 180-kHz synchronous buck controller. The output voltage is set with a single external resistor, allowing fine adjustments to the output voltage. To ensure proper operation, a compensated inductor current sense circuit is integrated with the controller to provide over-current protection. The internal soft start circuitry ensures a smooth power up sequence.The LTC3441EDE#TRPBF features frequency synchronization and current-mode-burst-mode mode operation as well as frequency foldback to reduce noise and improve efficiency at lower load currents. It is available in a tiny 10-lead DFN package and can operate over a temperature range of -40°C to +85°C.The LTC3441EDE#TRPBF is ideal for a wide range of end applications. It is designed for use in high-performance consumer electronics, telecom infrastructure, industrial, home appliance and computing applications. Its tiny package size and high efficiency make it an ideal choice for space-constrained designs.In conclusion, the LTC3441EDE#TRPBF is a feature-rich, high-performance controller for building efficient and reliable DC/DC converters. It is versatile and cost-effective, making it an ideal choice for a variety of point-of-load (PoL) applications.
