RT6260C

10A, 23V Synchronous Step-Down Converter with 5V LDO

RT6260C
New

The RT6260C is an advanced constant on-time (ACOTTM) mode synchronous buck converter. The main control loop of the RT6260C uses an advanced constant on-time (ACOTTM) mode control which provides a very fast transient response. The RT6260C operates from 5.1V to 23V input voltage.

Applications

  • Industrial and Commercial Low Power Systems
  • Computer Peripherals
  • LCD Monitors and TVs
  • Green Electronics/Appliances
  • Point of Load Regulation for High-Performance DSPs, FPGAs, and ASICs
