Product Overview
The RT8293BHZSP from Richtek is a 3A, 23V, 1.2MHz synchronous step-down converter in 8 pin SOP package. This is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 3A output current from a 4.5V to 23V input supply. The RT8293B's current mode architecture and external compensation allow 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. The RT8293B provides output under voltage protection and thermal shutdown protection. The low current (<lt/>3μA) shutdown mode provides output disconnect, enabling easy power management in battery powered systems. It is used in wireless AP/router, set-top-box, LCD monitors and TVs, green electronics/appliances, point of load regulation of high-performance DSPs, industrial and commercial low power systems.
