6A, 2MHz, High Efficiency Synchronous Step-Down Converter

RT8073

The RT8073 is a high efficiency PWM step-down converter and capable of delivering 6A output current over a wide input voltage range from 2.9V to 5.5V.

The RT8073 provides accurate regulation for a variety of loads with an ±1% reference voltage at room temperature. For reducing inductor size, it provides up to 2MHz switching frequency. The efficiency is maximized through the integrated 50mΩ for high side, 35mΩ for low side MOSFETs and 250μA typical supply current.

The RT8073 features over current protection, frequency fold back function in shorted circuit, hiccup mode under voltage protection and over temperature protection.

The RT8073 is available in SOP-8 (Exposed Pad) and WDFN-12L 3x3 packages.
