RT8079GQW

The RT8079GQW is a 2.95V to 6V input, 3A output, 2MHz, synchronous step-down converter in 16 pin WQFN package. The RT8079 provides accurate regulation for a variety of loads with ±3% accuracy. For reducing inductor size, it provides up to 2MHz switching frequency. The efficiency is maximized through the integrated 45mohm MOSFETs and 550μA typical supply current. Under voltage lockout voltage of the RT8079 is 2.7V and it also provides external setting by a resistor network on the enable pin. It provides protections such as inductor current limit under voltage lockout and thermal shutdown. The RT8079's current mode architecture allows the transient response to be optimized over a wider input voltage and load range. Cycle by cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up. It is used in low-voltage, high-density power systems, distributed power systems and point-of load conversions.
