Richtek RT8072

Description

The RT8072 is a high efficiency PWM step-down converterand capable of delivering 5A output current over a wideinput voltage range from 2.9V to 5.5V.The RT8072 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 RT8072 features over current protection, frequencyfold back function in shorted circuit, hiccup mode undervoltage protection and over temperature protection.The RT8072 is available in SOP-8 (Exposed Pad) andWDFN-12L 3x3 packages.
