RT7266

3A, 18V, 700kHz ACOT® Synchronous Step-Down Converter

RT7266
New

The RT7266 is an adaptive on-time ACOTTM mode synchronous buck converter. The adaptive on-time ACOTTM mode control provides a very fast transient response with few external components. The low impedance internal MOSFET can support high efficiency operation with wide input voltage range from 4.5V to 18V . The proprietary circuit of the RT7266 enables to support all ceramic capacitors. The output voltage can be adjustable between 0.765V and 8V. The soft-start is adjustable by an external capacitor.

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
