Product Overview 

The SY8113 is a high-efficiency 500 kHz synchronous step-down DC-DC converter capable of delivering 3A. The SY8113 has a wide input voltage range of 4.5V to 18V and integrates a main and synchronous switch with very low on-resistance RDS(ON) to minimize conduction losses. The 500 kHz switching frequency enables low output voltage ripple and reduces the size of external inductors and capacitors. It features an instant PWM architecture for fast transient response in high-step-down applications.
