fitipower integrated technology lnc. FP6375 High Efficiency 1MHz 28.55AT Synchronous Step Down Regulator Description The FP6375 is a high-efficiency 1MHz synchronous step-down DC-DC regulator and capable of delivering output current up to 2.5A. The FP6375 operates over wide input voltage range from 2.7V to 5.5V, and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. Low output voltage ripple, small external inductor and capacitor sizes are achieved with 1MHz switching frequency. Pin Assignments S5 Package (SOT-23-5) FB VIN 54 (Marking) 123 EN GND LX Figure 1.
