http://www.richtek.com/assets/product_file/RT2856H/DS2856H-05.pdf6A, 18V, Synchronous Step-Down ConverterThe RT2856H 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 RT2856H current-mode architecture with external compensation allows the transient response to be optimized over a widerange of loads and output capacitors. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during startup. Fault condition protections include output under-voltageprotection, output over-voltage protection, and overtemperature protection. The low current shutdown mode provides output disconnection, enabling easy power management in battery-powered systems.
