L296 Description

Short technical summary and product information.

The L296 is a step-down (buck) switching regulator IC manufactured by STMicroelectronics. It is designed to provide a positive adjustable output voltage from 5.1V to 40V with a maximum output current of 4A. The device operates with an input voltage range from 9V up to 46V, making it suitable for a variety of power supply applications.

 

Key electrical specifications include a minimum efficiency of 90% and a typical switching frequency of 100kHz (maximum 200kHz). The regulator features a single output with an adjustable output voltage, and it does not include a synchronous rectifier. The IC can dissipate up to 20W of power and is rated for a junction temperature range of -40°C to 150°C.

 

The L296 is housed in a 15-lead Multiwatt package, which is a through-hole mounting style suitable for PCB designs requiring adequate heat dissipation. This package allows for efficient thermal management in high-power applications.

 

Typical applications include use in industrial power supplies, battery chargers, and distributed power systems where a high-current adjustable step-down conversion is needed. The device's robust temperature range and high efficiency make it a reliable choice for demanding environments.
