1.2MHz, 1A Synchronous Step-Down DC/DC Converter

General Description

The FAN8060 is a highly efficient, monolithic, currentmode, step-down synchronous regulator. It can provide 1A continuous current from 2.5V to 5.5V input voltage. The output voltage can be adjusted from 1.2V up to the input voltage with an external voltage divider. External compensation and soft-start allow for design optimization and flexibility. High-frequency operation allows for all-ceramic solutions and small footprints. In addition, a user-selectable current limit provides protection against output overload and short circuit. FAN8060 features pulse skipping to achieve higher efficiency during light load operation. 100% duty cycle capability enables power solutions to extend the drop out voltage. Provision for external synchronization allows users to minimize input capacitors and manage EMI in solutions. FAN8060 is available in a green, low profile, 10-Lead 3x3mm MLP package.
