描述 Description

The TJ6813 high-efficiency, DC-DC step-down switching regulator delivers up to 3A of output current.
The device operates from an input voltage range of 2.8V to 5.5V and provides an adjustable output voltage from0.8V to VIN*0.9, making the TJ6813 ideal for on-board post regulation applications. The efficiency of TJ6813 atlight load (10mA) is up to 80%, and efficiency at heavy load is up to 94%.The TJ6813 operates at a fixed frequency of 1MHz. The high operating frequency minimizes the size ofexternal components. Internal soft-start circuitry reduces inrush current. Short-circuit and thermal-overloadprotection improve design reliability.
