Introduction of LT3511HMS#TRPBF
The LT3511HMS#TRPBF is a low-dropout (LDO) regulator designed for mobile applications. It is a high-efficiency, low-stdby current, low-output noise, ultra-low noise dual supply DC-DC switching regulator with adjustable output voltage and current. The device integrates two thermal shut-down circuits and two power management systems, which together provide low-cost, high-efficiency, fault-tolerant, low-standby current and low-output noise dual supply designs. The LT3511HMS#TRPBF device is available in 5V/3.3V and 5V/3V configurations.Application Field of LT3511HMS#TRPBF
The LT3511HMS#TRPBF device is most commonly used in applications such as mobile phones, tablets, portable medical devices, and other portable or embedded products that require high efficiency and low noise dual power supplies. It is well-suited for applications such as LCD/ LED display drivers, RF/GPS/Bluetooth communication systems, audio amplifiers, and other low-power, efficient systems.Working Principle of LT3511HMS#TRPBF
The LT3511HMS#TRPBF uses two independent buck converters to generate 3V and 3.3V output and two linear regulatosr to generate reference voltage and current. The buck converter works at high frequency to maintain operationally efficiency (typical 93 % efficiency). It is capable of delivering output current up to 2A with a minimum dropout voltage of 0.6V. The two linear regulators provide reference voltage (1.2V) and current (100 uA). Both of these regulators can be remotely controlled via two pins (ADCREF, REFCNT) and are power management systems. The LT3511HMS#TRPBF device features two integrated thermal shut-down circuits. The first is the Internal Over-Temperature Shutdown (OTSD) circuit, which will be triggered when the internal die temperature exceeds approximately 150C.The second is the Junction Temperature Monitor Shutdown (JTSD) circuit, which will be triggered when the junction temperature exceeds approximately 165C. This OTSD and JTSD circuit significantly improves the thermal performance of the device and the reliability of the entire system.Conclusion
The LT3511HMS#TRPBF is a high-efficiency, low-stdby current, low-output noise, ultra-low noise dual supply DC-DC switching regulator with adjustable output voltage and current. It is most commonly used in applications such as mobile phones, tablets, portable medical devices, and other portable or embedded products that require high efficiency and low noise dual power supplies. It uses two independent buck converters to generate 3V and 3.3V output, and two linear regulators to generate reference voltage and current. The LT3511HMS#TRPBF also features two integrated thermal shut-down circuits for improved thermal performance and system reliability.The specific data is subject to PDF, and the above content is for reference
