Richtek RT8073

Description

6A, 2MHz, High Efficiency Synchronous Step-Down ConverterThe RT8073 is a high efficiency PWM step-down converterand capable of delivering 6A output current over a wideinput voltage range from 2.9V to 5.5V.The RT8073 provides accurate regulation for a variety ofloads with an ±1% reference voltage at room temperature.For reducing inductor size, it provides up to 2MHzswitching frequency. The efficiency is maximized throughthe integrated 50mΩ for high side, 35mΩ for low sideMOSFETs and 250μA typical supply current.The RT8073 features over current protection, frequencyfold back function in shorted circuit, hiccup mode undervoltage protection and over temperature protection.The RT8073 is available in SOP-8 (Exposed Pad) andWDFN-12L 3x3 packages.
