The RT6215E is a high-efficiency, monolithic synchronous step-down DC-DC converter that can deliver up to 2A output current from a 4.5V to 24V input supply. The RT6215E adopts advanced constant on-time (ACOTTM) architecture to provides a very fast transient response with few external components and keep in constant frequency. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up. Input under-voltage lock-out, output under-voltage protection, over-current protection, and over-temperature protection offer completely safe and smooth operation in all applied conditions.
