SY8368AQQC数据手册Silergy中文资料规格书

描述 Description

The SY8368A develops a high efficiency synchronous step-down DC-DC regulator capable of delivering 8A continuous, 16A peak current. The SY8368A operates over a wide input voltage range from 4.0V to 28V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.\r
\r
The SY8368A 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
