General Description:

The SY8368A develops a high efficiency synchronousstep-down DC/DC regulator capable of delivering 8Acontinuous, 16A peak current. The SY8368A operatesover a wide input voltage range from 4.0V to 28V andintegrates main switch and synchronous switch withvery low RDS(ON) to minimize the conduction loss.The SY8368A adopts the instant PWM architecture toachieve fast transient responses for high step downapplications and high efficiency at light loads. Inaddition, it operates at pseudo-constant frequency of800kHz under continuous conduction mode tominimize the size of inductor and capacitor.

Features:

 4.0-28V Wide Input Voltage Range

 Low RDS(ON) for Internal Switches: 20/10mΩ
