6A, 23V Synchronous Step-Down Converter

RT6306A

Update Alert Share

The RT6306A is an advanced constant on-time (ACOT®) mode synchronous buck converter. The main control loop of the RT6306A uses an advanced constant on-time (ACOT®) mode control which provides a very fast transient response. The RT6306A operates from 4.5V to 23V input voltage, and the output voltage can be programmed between 0.6V to 5.1V.

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
