Product details
Overview
The ST8033 is a fully integrated, high-efficiency 3A synchronous rectified step-down converter that operates at high efficiency over a wide output current load range. This device offers two operation modes, PWM control and PFM mode switching control, which allows high efficiency over a wider range of the load. The ST8033 requires a minimum number of readily available standard external components and is available in SOT23-6 package.
