TL497ACDR Description

Short technical summary and product information.

The Texas Instruments TL497ACDR is a DC/DC switching voltage regulator designed for step-up, step-down, and inverting applications. It incorporates all active functions required for building switching voltage regulators and can also serve as a control element for higher-power outputs.

 

Key electrical specifications include a wide input voltage range from 4.5V to 12V, with an adjustable output voltage ranging from -25V to 30V. The device offers a peak switch current of 500mA and features like TTL-compatible inhibit and soft start-up capability. It operates with a typical quiescent current of 0.011A and achieves efficiencies of 60% or greater.

 

The TL497ACDR is housed in a 14-SOIC package, suitable for surface mount applications. Its operating temperature range is from 0°C to 70°C (TA). The regulator provides good input and output regulation, with typical values of 0.2% and 0.4% respectively.

 

This component is well-suited for designs requiring flexible voltage conversion, offering both positive and negative output configurations. Its fixed-on-time, variable-frequency control circuit is programmed by a single external capacitor, simplifying design.
