LM2576HVS-12 Description

Short technical summary and product information.

The LM2576HVS-12 is a monolithic integrated circuit designed as a step-down (buck) switching regulator. It is capable of driving a 3A load with excellent line and load regulation. This device features a fixed output voltage of 12V and requires minimal external components for operation, including internal frequency compensation and a fixed-frequency oscillator.

 

The regulator operates with an input voltage range of up to 57V for the HV version and has a guaranteed output current of 3A. It features a fixed oscillator frequency of 52kHz and includes protection mechanisms such as cycle-by-cycle current limiting and thermal shutdown for fault conditions. The LM2576HVS-12 is suitable for applications requiring high-efficiency step-down conversion.

 

Packaged in a TO-263-5L surface-mount package, this component is designed for efficient power management solutions. Its design simplifies the creation of switch-mode power supplies, offering a high-efficiency alternative to linear regulators and potentially reducing the need for large heat sinks.
