SA23002B Datasheet | Silergy

General Description The SA23002B high efficiency 2.35MHz synchronous buck converter operates over an input voltage range of 2.8V to 5.5V and can deliver an output current up to 2A. It integrates a top MOSFET and a bottom MOSFET with very low RDS(ON) to minimize conduction loss. The 2.35MHz constant switching frequency reduces the required external inductor and capacitor values. The SA23002B uses a peak current mode control architecture. It operates in fixed frequency pulse width modulation (PWM) mode at medium to heavy loads, and in pulse frequency modulation (PFM) mode during light loads, thereby maintaining high efficiency over the entire load current range. It also provides...
