LM2575YWM Description

Short technical summary and product information.

The LM2575YWM from Microchip Technology is a monolithic integrated circuit designed for step-down (buck) switching regulator applications. It is capable of driving a 1A load with excellent line and load regulation. This series offers fixed output versions (3.3V, 5V, 12V) and adjustable versions with an output voltage range from 1.23V to 37V.

 

The LM2575YWM features a wide input voltage range of 4V to 40V and a fixed switching frequency of 52kHz. It requires a minimum number of external components, including internal frequency compensation and a fixed-frequency oscillator, simplifying power supply design. The device includes thermal shutdown and cycle-by-cycle current limiting for protection under fault conditions.

 

This regulator is available in a 24-SOIC surface mount package. It operates within a temperature range of -40°C to 85°C. The LM2575 series provides a high-efficiency replacement for linear regulators, often eliminating the need for a heat sink.
