SY8204 Description
SY8204 develops a high efficiency synchronous stepdown DC-DC converter capable of delivering 4A output current. SY8204 operates over a wide input voltage range from 4.5V to 30V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. SY8204 adopts the proprietary instant PWM architecture to achieve fast transient responses for high step down applications and high...
