Suitable for use in SnPb or Pb-free soldering processes. Pin Configurations (TOP VIEW) Applications Wireless AP/Router Set-Top-Box Industrial and Commercial Low Power Systems LCD Monitors and TVs Green Electronics/Appliances Point of Load Regulation of High-Performance DSPs SOP-8 (Exposed Pad) 3A, 17V, 340kHz Synchronous Step-Down Converter General Description The RT7253A is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 3A output current from a 4.5V to 17V input supply. The RT7253A'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 RT7253A also provides under voltage protection and thermal shutdown protection. The low current (<3 μA) shutdown mode provides output disconnection, enabling easy power management in battery-powered systems. The RT7253A is available in an SOP-8 (Exposed Pad) package.
