The TL497ACN from Texas Instruments is a fixed-on-time, variable-frequency switching voltage regulator control circuit. It is designed for ease of use in step-up, step-down, or voltage-inversion applications requiring high efficiency, achieving 60% or greater.
Key electrical specifications include a maximum input voltage of 12V and a minimum of 4.5V, with an adjustable output voltage ranging from -25V to 30V. The device can handle a peak switch current of 500mA and features a typical quiescent current of 0.011A. Input regulation is typically 0.2%, and output regulation is typically 0.4%.
This regulator incorporates all active functions required for building switching voltage regulators and can also serve as a control element for higher-power applications. It supports nonsynchronous rectification and includes an enable feature. The operating temperature range is from -40°C to 85°C.
The TL497ACN is available in a 14-PDIP package and is suitable for through-hole mounting. Its adjustable output and multiple topology support (Buck, Boost, Flyback, Forward, SEPIC) make it a flexible component for various power management designs.
