SY8301数据手册Silergy中文资料规格书

描述 Description

The SY8301 develops a high efficiency synchronous step-down DC/DC converter capable of delivering 1A load current. The SY8301 operates over a wide input voltage range from 4.5V to 40V and integrates main switch and synchronous switch with low RDS(ON) to minimize the conduction loss.\r
\r
The SY8301 adopts peak current control scheme. The switching frequency is 2MHz. Low output voltage ripple and small external inductor and capacitor sizes are achieved with 2MHz switching frequency.\r
\r
The device also features ultra low quiescent operating to achieve high efficiency under light load. And the internal soft-start limits inrush current during power on.
