EVB_RT2856GQW

RT2856GQW 6A, 18V, synchronous step-down converter evaluation board. The RT2856GQW 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 RT2856GQW 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 overtemperature protection. The low current shutdown mode provides output disconnection enabling easy power management in battery-powered systems.
