The SA23002C 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 SA23002C uses a peak current mode control architecture. It operates in fixed frequency pulse width modulation (PWM) mode at light to heavy loads, thereby maintaining small output voltage ripple over the entire load current range. It also provides cycle-by-cycle current limit protection, output short-circuit protection, and overtemperature protection.
The SA23002C is available in a compact DFN1.4×1.8-6 package.
