LM2575GR-12 Description

Short technical summary and product information.

The LM2575GR-12 from HTC Korea is a monolithic integrated circuit designed for efficient step-down DC/DC conversion. It is capable of driving a 1A load without requiring an external transistor, saving board space. The device features a fixed switching frequency of 52kHz and utilizes voltage mode non-synchronous PWM control.

 

Available in fixed output voltage versions (3.3V, 5.0V, 12V) and an adjustable version with an output voltage range from 1.23V to 37V, the LM2575GR-12 offers design flexibility. It includes essential protection features such as thermal shutdown to prevent damage from over-temperature conditions and current limiting to protect the output switch against overcurrent operation.

 

The LM2575GR-12 is housed in a TO-263-5L package, suitable for surface mount applications. Its wide input voltage range and integrated compensation simplify external design, making it ideal for various power management applications including simple high-efficiency buck regulators and on-card switching regulators.
