SY8205 Datasheet (Silergy) - Synchronous Step Down Regulator

SY8205, Synchronous Step Down Regulator

SY8205 develops a high efficiency synchronous stepdown DC-DC converter capable of delivering 5A output current.

SY8205 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.

SY8205 adopts th

SY8205 Features

* Low RDS(ON) for internal switches (top/bottom): 70/40 mΩ

* 4.5-30V input voltage range

* Instant PWM architecture to achieve fast transient responses

* External softstart limits the inrush current

* Pseudo-constant frequency: 500kHz at heavy loads
