L7983PUR Description

Short technical summary and product information.

The STMicroelectronics L7983PUR is a synchronous step-down (buck) converter designed for efficient power management. It features an adjustable output voltage and can handle a current of up to 300mA. The device operates with a wide switching frequency range from 200kHz to 2.2MHz, allowing for flexibility in design.

 

This regulator is suitable for various applications requiring a stable, lower output voltage from a higher input. Its topology is a buck converter with a synchronous rectifier, enhancing efficiency. The operating temperature range is from -40°C to 150°C (TJ), making it robust for demanding environments.

 

The L7983PUR comes in a compact 10-DFN (3x3) package, specifically a 10-WFDFN Exposed Pad, designed for surface mounting. This packaging is ideal for space-constrained applications where efficient heat dissipation is also a consideration.
