The FAN8060 is a highly efficient, monolithic, current-
mode, step-down synchronous regulator. It can provide
1 A continuous current from 2.5 V to 5.5 V input
voltage. The output voltage can be adjusted from 1.2 V
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
3x3 mm MLP package.
