LYT4216E2 Datasheet/PDFLYT4216E2 application field and working principle
LYT4216E2 is a high-efficiency monolithic synchronous boost regulator from Shenzhen LY Technologies. It is built primarily for AC/DC converters, offline switchers, and other medium-power applications. In this article, we will discuss the application fields and working principles of the device.The LYT4216E2 is designed for applications with a maximum input voltage of up to 40V and a maximum output voltage of 5V or 7V. It is a single-phase boost regulator that can be used in a variety of applications such as LED Lighting, embedded systems, automotive electronics, and other portable applications. The device provides up to 95% efficiency with a minimum quiescent current of only 16μA. The device offers a wide range of features including an adjustable switching frequency, an adjustable peak current limit, an internal soft start, adjustable power-good function, and an adjustable output voltage trim.The working principle of the LYT4216E2 is based on a synchronous buck design. It consists of two switches, a low-side switch and a high-side switch, connected in series with a storage inductor. The low-side switch is connected to the input voltage supply and the high-side switch is connected to the output voltage rail. When a supply voltage is applied, the low-side switch is turned ON and the energy is stored in the inductor. Once the required current is reached, the low-side switch is turned OFF and the high-side switch is turned ON to discharge the stored energy and provide the output voltage.The LYT4216E2 also provides various protection features such as over temperature protection, over voltage protection, under voltage lockout protection, over current protection, short circuit protection, and EMI filtering. This makes it a highly reliable device for powering various applications.The LYT4216E2 is a high-efficiency, high-reliability solution for power management in applications such as AC/DC converters, offline switchers, and other medium-power applications. It provides a wide range of features and protection mechanisms which make it easy to use and reliable.
