FAN8303 - Non-Synchronous Step-Down DC/DC Regulator

General Description

The FAN8303 is a monolithic, non-synchronous, stepdown (buck) regulator with internal power MOSFETs.

It achieves 2A continuous output current over a wide input supply range with excellent load and line regulation.

Current-mode operation provides fast transient response and eases loop stabilization.

Key Features

  • 2A Output Current 0.22Ω Internal Power MOSFET Switch Wide 5V to 23V Operating Input Range Output Adjustable from 0.6 to 20V Stable with Low ESR Output Ceramic Capacitors Up to 90% Efficiency Less than 40µA Shutdown Current Fixed 370kHz Frequency Thermal Shutdown with Hysteresis Cycle-by-Cycle Over-Current Protection Available in 8-Pin SOIC Package.
