SY8121 Description
SY8121 develops high efficiency synchronous stepdown DC-DC converter capable of delivering 2A load current. SY8121 operates over a wide input voltage range from 4.5V to 18V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. SY8121 adopts the instant PWM architecture to achieve fast transient responses for high step down applications and high efficiency at light...
