< et >The SC4519STRT is a high efficiency, cost effective, programmable synchronous Buck DC/DC switching regulator that delivers up to 5A current in SOP-8 packaging. It contains two internal high-side and two low-side MOSFETs, and operates with input voltages ranging from 2.3V to 5.5V. The SC4519STRT incorporates a high-efficiency control architecture to maximize efficiency, reduce shutdown current and extends battery life. It can program the output voltage from 0.6V to 3.3V, with excellent line and load regulation. The switching frequency with an external resistor can be adjusted from 300KHz to 2MHz, and internal soft-start allows for smooth power-up. The SC4519STRT can be enabled or disabled through an appropriate logic signal on the enable pin, and in shutdown-mode (EN = 0V) the quiescent current consumption is only 2.5uA.The module also has a built-in thermal protection circuit that limits the total power consumption and protects the load from any kind of damage, such as over-temperature, over-current, over-voltage and over-power conditions.The SC4519STRT offers both PWM and PFM modes, benefiting the design with high-efficiency at both heavy and light-loads. It is designed on CMOS technology with high operating temperature ranges and maximum power conversion efficiency.The SC4519STRT is ideal for applications such as industrial, medical, automotive, communications, consumer and more. It provides cost-effective and reliable power conversion and monitoring solution that helps system designers to reduce their product size, increase efficiency and enhance their system’s performance.In summary, the SC4519STRT is a high-efficiency, cost-effective synchronous Buck DC/DC switching regulator, providing a versatile and reliable solution for various applications. It offers wide input voltage range, high output current, adjustable switching frequency, excellent line and load regulation, built-in thermal protection and comprehensive protection features, helping to reduce size, increase efficiency and provide reliable power supply.
