Product Summary

The ACT4070YH is a current-mode step-down DC/DC converter that generates up to 3A output current at 400 kHz switching frequency. The device utilizes Active-Semi’s proprietary ISOBCD30 process for operation with input voltage up to 30V. Consuming only 6μA in shutdown mode, the ACT4070YH is highly efficient with peak efficiency at 95% when in operation. Protection features include cycle-by-cycle current limit, thermal shutdown, and frequency fold back at short circuit. The device also includes an internal soft start function to prevent overshoot. The applications of the ACT4070YH include TFT LCD Monitors or Televisions and HDTV, Portable DVD Players, Car-Powered or Battery-Powered Equipment, Set-Top Boxes, Telecom Power Supplies, DSL and Cable Modems and Routers.
