2A, 23V, 340kHz Synchronous Step-Down Converter

RT8284

Update Alert Share

The RT8284 is a high efficiency, monolithic synchronous step-down DC-DC converter that can deliver up to 2A output current from a 4.5V to 23V input supply. The RT8284'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 RT8284 also provides under voltage protection and thermal shutdown protection. The low current (< 3μA) shutdown mode provides output disconnect, enabling easy power management in battery powered systems. The RT8284 is a available in a SOP-8 and SOP-8 (Exposed Pad) package.
