The TL497ACNE4 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 peak switch current of 500 mA, an input voltage range of 4.5V to 12V, and an adjustable output voltage with a maximum of 30V and a minimum of -25V. The device features typical quiescent current of 0.011A, input regulation of 0.2%, and output regulation of 0.4%. It supports multiple topologies including Boost, Buck, Flyback, Forward, and SEPIC.
This regulator incorporates active functions for constructing switching voltage regulators and can also serve as a control element for high-power-output applications. It includes features such as TTL-compatible inhibit, soft start-up capability, and input current limit protection. The operating temperature range is from -40°C to 85°C.
The TL497ACNE4 is available in a 14-pin PDIP package and is designed for through-hole mounting.
