LM2575WU Description

Short technical summary and product information.

The LM2575WU from Microchip Technology is a monolithic integrated circuit that functions as a step-down (buck) switching regulator. It is designed to provide a 1A load current with excellent line and load regulation. This series offers an adjustable output voltage range from 1.23V to 37V, simplifying the design of switch-mode power supplies by requiring a minimum number of external components.

 

Key electrical specifications include a wide input voltage range of 4V to 40V and a fixed internal oscillator frequency of 52kHz. The regulator includes features such as cycle-by-cycle current limiting and thermal shutdown for protection under fault conditions. It is an efficient replacement for linear regulators, often eliminating the need for a heat sink.

 

The LM2575WU is available in a TO-263-5 surface-mount package, suitable for various electronic designs. It operates within a temperature range of -40°C to 85°C. The device also features a low power standby mode with typical current consumption below 200µA.
