FAN8303: Step-Down DC-DC Regulator, Non-Synchronous, 2 A, 23 V

  • The FAN8303 is a monolithic, non-synchronous, stepdown (buck) regulator with internal power MOSFETs. It achieves 2 A 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. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. The regulator draws less than 40 µA shutdown current. FAN8303 requires a minimum number of readily available standard external components.
    External compensation, enable, and programmable soft-start features allow design optimization and flexibility. Cycle-by-cycle current limit, frequency foldback, and thermal shutdown provide protection against shorted outputs.
