The TL497ACD from Texas Instruments is a DC/DC switching regulator designed for step-up, step-down, and inverting voltage 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 an input voltage range of 4.5V to 12V, with an adjustable output voltage ranging from -25V to 30V. The device can handle a peak switch current of 500mA and offers typical input regulation of 0.2% and output regulation of 0.4%. It operates with a low quiescent current of 0.011A (typical).
This regulator supports both buck and boost topologies, featuring nonsynchronous rectification. It is designed for ease of use and high efficiency, rated at 60% or greater. The TL497ACD is available in a 14-SOIC package, suitable for surface mount applications.
Features include TTL-compatible inhibit and soft-start capability, making it adaptable for various power management designs. The fixed-on-time, variable-frequency control circuit is programmed by a single external capacitor.
