Application Fields

LTC1261LIS8-4.5#PBF is widely used in industrial and home electric equipment, especially in high-current and low-voltage application systems. The Vin can reach up to 28V, and the Vout can be easily designed to fit the user’s needs. Its excellent power conversion efficiency of up to 83%, make it an irresistible choice in situations that requires long-term high-efficiency operation.

Features

The core of the LTC1261LIS8-4.5#PBF is a professional integrated high-speed MOSFET, combined with features such as a high-speed current-sense amplifier, fast transient response, reversed-voltage protection, and over-voltage protection. The reverse-current protection circuit can prevent any unwanted current flow in the case of reverse connection, providing secure operation. Moreover, its soft start feature can be used to prevent system overload during the startup process.

Working Principle

LTC1261LIS8-4.5#PBF adopts a synchronous rectification mode of self-oscillating switching components to control the voltage output. In the process of voltage output, the pulse width of the internal high-speed amplifier is constantly changed according to the load current feedback, so that the voltage output always remains stable.

Quasi-resonant switching regulator separates the oscillation frequency into two parts, the constant frequency and the variable frequency, so that the efficiency can be maximized during the vibration process.

LTC1261LIS8-4.5#PBF product adopts OFF-Time control architecture, with a quasi-resonant clock frequency switch, so that under its regulation, the output voltage can maintain high stability and accurate regulation at any load. Meanwhile, the OFF-Time control architecture can effectively suppress the EMI noise, ensuring excellent performance.

Protection Functions

The LTC1261LIS8-4.5#PBF can protect itself and the system from abnormal situations, making it safer and more reliable. Through its over voltage protection circuit, reverse current protection circuit, and thermal shut-down circuit, any failure or abnormal conditions can automatically be shut off. The fault protection and system protection offer a reliable safeguard for the device.

Conclusion

As a DC/DC switching regulator controller, the LTC1261LIS8-4.5#PBF has excellent performance and features, making it suitable for applications such as computer peripherals, digital products, power supplies and battery power systems. The wide range of features, protection functions, and stable performance, make the LTC1261LIS8-4.5#PBF an excellent choice for industrial and home device manufacturers.
