This post explains for the semiconductor SY8208A, SY8208AQNC.
The Part Number is SY8208A.
The Package is QFN3x3-10.
The function of this semiconductor is Synchronous Step Down Regulator.
Manufacturers : Silergy
The SY8208A develops a high efficiency synchronous step-down DC-DC regulator capable of delivering 8A continuous, 16A peak current. The SY8208A operates over a wide input voltage range from 4V to 28V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
The SY8208A adopts the instant PWM architecture to achieve fast transient responses for high step down applications and high efficiency at light loads. In addition, it operates at pseudo-constant frequency of 800kHz under continuous conduction mode to minimize the size of inductor and capacitor. […]
