TDA38806 Overview
The TDA38806 is a 6 A fully integrated and highly efficient DC - DC Buck regulator. It uses a fast Constant On-Time (COT) control scheme, which simplifies the design efforts and achieves fast control response during the transients while maintaining excellent line and load regulation. It can operate over a wide range of input voltage (2.7 V to 16 V) using an external bias supply.
