2A, 1MHz, 6V CMCOT Synchronous Step-Down Converter

RT8097B

Update Alert Share

The RT8097B is a high efficiency synchronous step-down DC-DC converter. Its input voltage range is from 2.7V to 6V and provides an adjustable regulated output voltage from 0.6V to 3.4V while delivering up to 2A of output current.

The internal synchronous low on-resistance power switches increase efficiency and eliminate the need for an external Schottky diode. The Current Mode Constant-On-time (CMCOT) operation with internal compensation allows the transient response to be optimized over a wide range of loads and output capacitors. The RT8097B is available in the SOT-23-5/6 package.

Applications

  • STB, Cable Modem, & xDSL Platforms
  • LCD TV Power Supply & Metering Platforms
  • General Purpose Point of Load (POL)
  • Internet of Things
