LM3578AN Description

Short technical summary and product information.

The Texas Instruments LM3578AN is a bipolar switching regulator designed for DC-to-DC voltage conversion. It supports multiple topologies including buck, boost, and buck-boost configurations, offering design flexibility.

 

This device operates from an input voltage range of 2V to 40V and can deliver an output current of up to 750mA. It features a typical switching frequency of 20kHz, though the introtext mentions 24kHz, indicating a potential data conflict that may require datasheet verification. The LM3578AN includes an internal 1.0V reference, simplifying circuit design.

 

Available in an 8-pin PDIP package, the LM3578AN is suitable for through-hole mounting. Its operating temperature range is specified from 0°C to 70°C (TA) according to the database, while the manufacturer page indicates a broader range of 0°C to 125°C. This part is designed with features like current limit and thermal shutdown for protection.

 

The LM3578AN is a nonsynchronous rectifier type. It is suitable for applications requiring efficient voltage conversion in a compact form factor.
