1.5MHz, 1A High Efficiency Step-Down Converter

RT8060

Update Alert Share

The RT8060 is a current mode, high efficiency PWM step-down DC/DC converter that can support a wide input voltage range from 2.7V to 5.5V, while delivering up to 1A output current. The current mode operation provides fast transient response and eases loop stabilization.
A 1.5MHz frequency operation allows the use of a smaller inductor to meet the space and height limitations handheld applications.
The RT8060 is available in a SOT-23-5 package.

Applications

  • Storage Device : HDD/ODD
  • Wireless and DSL Modems
