General Description

ETA1478 is a wide input range, high-efficiency and high frequency DC-to-DC step-down switching regulator, capable of delivering up to 2A of output current.

With a fixed switching frequency of 500KHz, this current mode PWM controlled converter allows the use of small external ponents, such as ceramic input and output caps, as well as small inductors.

ETA1478 also employs a proprietary control scheme that switches the device into a power save mode during light load, thereby extending the range of high efficiency operation.

Key Features

  • Wide Input Range: 4.5V-18V.
  • High Efficiency PFM mode at light load.
  • Capable of Delivering 2A.
  • No External Compensation Needed.
  • Current Mode Control.
  • Thermal Shutdown and UVLO.
  • Excellent Load and Line Transient Response.
  • Available in SOT23-6 Package.
