Product Summary

The ACT4088 is a current-mode step-down DC/DC converter that supplies up to 1.5A into 5V from a 12V input. 1.4MHz switching frequency allows the use of tiny external components, and internal loop compensation provides simple, stable power supplies with a minimum of external components. Optimized for use with ceramic input and output capacitors, the ACT4088 provides a very compact 1.5A power supply for space constrained mobile and consumer applications. The applications of the ACT4088 include TFT LCD Monitors, Portable DVDs, Headphones, MP3 Players, etc, Car-Powered or Battery-Powered Equipment, Set-Top Boxes, Telecom Power Supplies, DSL and Cable Modems and Routers.
