The RTQ2816 is a high efficiency, monolithic synchronous step-down DC-DC ,converter that can deliver up to 6A output current from a 4.5V to 18V input ,supply. The RTQ2816 current-mode architecture with external compensation allows ,the transient response to be optimized over a wide range of loads and output ,capacitors. Cycle-by-cycle current limit provides protection against shorted ,outputs and soft-start eliminates input current surge during start-up. Fault ,condition protections include output under-voltage protection, output ,over-voltage protection, and over-temperature protection. The low current ,shutdown mode provides output disconnection, enabling easy power management in ,battery-powered systems.
