General Description

/ORDERING INFORMATION TPS65276V is a monolithic dual synchronous buck converter with wide 4.5V to 18V operating input voltage range that encompassed most intermediate bus voltage operating off 5-, 9-, 12- or 15-V power bus or battery.

The converter with constant frequency peak current mode control is designed to simplify its application while giving the designers options to optimize their usage according to the target applications.

Each buck converter in TPS65276V has external feedback resistors that can be used for setting the initial start up voltage.
