1.5MHz,30V,1.2A FPWM Synchronous Step-Down Converter

Description

l The SL2359 is a high efficiency 1.5MHz,synchronous step-down DC-DC converter capableof delivering up to 1.2Acurrent with force PWM operation and adopts COT control with fasttransient response performance. SL2359integrates both high and low side switch with lowRDS(ON) to minimize the conduction loss.Low output voltage ripple and small external inductor andfrequency.capacitor size are achieved with1.5MHzswitching

l The SL2359 requires a minimum number of readily available standard external components and is available in a 6-pin SOT23-6 RoHScompliant package.
