The TL497ACDG4 voltage regulator is an integrated DC-DC converter, capable of providing output voltage at 2.7V - 5.5V adjustable with an input voltage range of 2.7V – 5.5V. It features a high power conversion efficiency at low input voltage, allowing the TL497ACDG4 to be used in many applications such as power management, automotive electronics, industrial controls, and communications. The device integrates both the DC-DC buck step-down and the synchronous rectifier on a single chip, and the internal power switch supports P-channel and N-channel MOSFETs. Moreover, TL497ACDG4 is capable of working with high-accuracy temperature sensing and feedback control that can eliminate the need for an external temperature compensators.

The TL497ACDG4 is a self-contained, cost effective DC-DC controller with adjustable power switching, current limiter, and voltage regulator. The internal voltage sense circuit, coupled with the integrated control logic, isolates the output voltage from being influenced by external loading. This feature makes the TL497ACDG4 ideal for applications that require high dynamic stability, such as automotive and industrial electronics. The device operates at up to 1.5MHz switching frequency, allowing high power and efficiency to be achieved even at low input voltages and reducing external component count.

The device offers protection features such as integrated soft-start, thermal shutdown, and advanced current limiting for overcurrent protection. Thermal Shut Down (TSD) feature recognized high temperature and provide a thermal protection, preventing the device from overheating and damaging the system. The advanced current limiting lets TL497ACDG4 handle large transients without overshoot and control the inrush current.

The TL497ACDG4 provides many benefits for applications that require high efficient power management. It is optimized to support the latest architectures, provides fast transient recovery, and it can reduce the number of programmed firmware or external components required in the system. The device also offers improved reliability and performance, making it suitable for use in a wide range of applications, ranging from automotive and industrial electronics to power management and communications.
