FPWM Synchronous Step-Down Converter,synchronous step-down DC-DC converter,SL2359,SLKOR

The SL2359 is a high-efficiency 1.5MHz, synchronous step-down DC-DC converter capable of delivering up to 1.2A current with force PWM operation and adopts COT control with fast transient response performance. SL2359 integrates both high and low side switch with low R_DS(ON) to minimize the conduction loss. Low output voltage ripple and small external inductor and capacitor size are achieved with 1.5MHz switching. The SL2359 FPWM Synchronous Step-Down Converter requires a minimum number of readily available standard external components and is available in a 6-pin SOT23-6 RoHS-compliant package.
