LT8650SEV#PBF Application Field and Working Principle
The LT8650SEV#PBF is a high-performance, high-efficiency, dual current limit, step-down switching regulator from Linear Technology. It is a DC-DC converter from the company’s PMIC (Power Management IC) product line and comes in a 10-pin MSOP (Micro Small Outline Package) package that makes the device suitable for space-constrained applications. It has a 0.74V to 7V input voltage range and adjustable output voltage from 0.5V to 6V, making it suitable for many different applications.
Since it is a dual current limit switching regulator, it can reduce power consumption and improve system efficiency by using two independent current limit thresholds, allowing for improved protection in applications with high load current drops. The dual current limit feature also allows multiple output regulation modes, such as constant current type and constant voltage type, which can be selected based on the loading requirements of different types of applications. The LT8650SEV#PBF can also provide over temperature protection, fault protection, and load disconnection features.
The LT8650SEV#PBF is a high-efficiency DC-DC switching regulator, which uses a switching frequency of 500KHz and is designed to minimize the power consumption of the system. The device uses an internal voltage regulator and operates with a switching buck-boost mode, so it can process input voltages above, below or equal to its output voltage. The LT8650SEV#PBF can also be used in isolated systems and supports remote sensing, allowing the output voltage to be accurately set.
The LT8650SEV#PBF is a highly efficient DC-DC switching regulator, with up to 95% efficiency, that can be used in a wide range of applications, from general purpose applications to automotive and industrial applications. The device is suitable for systems that demand high efficiency, such as solar panel-powered systems, electronic appliances, and white goods. It is also suitable for automotive applications, such as in vehicle infotainment systems, as it can provide consistent power supply in harsh environments.
The working principle of the LT8650SEV#PBF is fairly simple. The device uses an oscillator to drive a power switch and a comparator to control the switch’s on and off times. When the oscillator turns the switch on, current flows through the inductor, while the outputs are disconnected. As the current builds up, the inductor accumulates energy, which is released when the oscillator turns the switch off and the magnetic field collapses. This energy is transferred through the diode, which protects the switch and the inductor by preventing the current from flowing in the opposite direction. The output capacitor is charged through the load, maintaining the output voltage.The LT8650SEV#PBF is an efficient, high-performance DC-DC switching regulator that is suitable for a wide range of applications. Its adjustable output voltage and dual current limit feature makes it highly suitable for automotive and industrial applications, and it can provide over temperature protection and fault protection for a improved safety.
