L7986ATR is a 10-V, 2-A buck regulator with advanced features from STMicroelectronics. It is the industry\'s only monolithic buck regulator that is both temperature- and current-sense compatible. The higher efficiency stands out from the other regulators and provides good heat dissipation with its efficient switching design.The L7986ATR offers excellent solution to many power management challenges, such as flexible adjustment and fast transient response. It integrates an on-chip temperature and current sensing of power supply components, allowing advanced regulation and control. This extends the lifetime of the system and improves safety.The primary application field of the L7986ATR is in DC-DC switching regulators. It can be used to provide a full range of step-down output voltages (from 2.5 V to 12 V) with high precision and fast response, from input voltages of up to 20 V. The device has an asynchronous rectifier, fast transient response and low current ripple.The L7986ATR also features a Power OK (PWD) signal to help protect the system from over-voltage or under-voltage conditions. It also features an over-temperature protection (OTP) module to protect from failure due to high or low temperatures. The devices also offer an important feature such as cycle-by-cycle current limit (CCL) for improved safety in the event of excessive current draw.The working principle of the L7986ATR is quite simple. It uses a switching controller that regulates the output voltage by modulating the pulse width of the switching element. It also uses an asynchronous rectifier to store energy, which is released during times of a decrease in the load current.The L7986ATR is a flexible, cost-effective solution that offers excellent performance and improved safety. Thanks to the device\'s temperature-sensing and current-limiting features, it is suitable for a wide range of industrial and consumer applications. It can be used to reduce power consumption and improve system efficiency, while offering reliable operation and improved safety.
