The LM21215MHE/NOPB is a synchronous buck regulator designed to operate within an input voltage range of 2.95 V to 5.5 V, delivering up to 15 A of continuous output current. It features integrated high-side and low-side FET switches with on-resistances of 7 m,Ѷ and 4.3 m,Ѷ, respectively, which contribute to its high efficiency. The output voltage is adjustable from 0.6 V to the input voltage, with a precision reference of ¬±1%. This device operates at a fixed switching frequency of 500 kHz and includes features such as adjustable current limit, soft start with an external capacitor, and output voltage tracking capability. It also incorporates internal protections including overvoltage protection (OVP), overcurrent protection (OCP), and under-voltage lockout (UVLO). The LM21215 is packaged in a thermally enhanced 20-pin HTSSOP with an exposed pad for improved thermal dissipation, making it suitable for applications in broadband, networking, and high-performance computing systems.
