LM25085SD/NOPB Description

Short technical summary and product information.

The LM25085SD/NOPB from Texas Instruments is a non-synchronous buck controller that operates with a wide input voltage range of 4.5V to 42V. This device utilizes a Constant On-Time (COT) control mode, enabling it to achieve ultra-fast transient response and nearly constant operating frequency with variations in line and load.

 

Key electrical specifications include an adjustable output voltage from 1.25V up to 42V, with a maximum output current capability of 10A. The switching frequency can be programmed up to 1MHz. The controller features adjustable current limit, enable functionality, and frequency synchronization. It requires no loop compensation.

 

Packaged in an 8-WSON (3x3) surface-mount package, the LM25085SD/NOPB is suitable for various power management applications. Its operating temperature range is -40°C to 125°C (TJ). The device also includes features such as internal soft-start and thermal shutdown for enhanced reliability.
