Product details

Description

SY8859 is a high efficient 1.0MHz synchronous step down DC/DC regulator capable of delivering up to 3A output current.

The SY8859 can operate over a wide input voltage range from 2.7V to 5.5V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

Features

Low RDS(ON) for Internal Switches (Top/Bottom) 85mΩ /50mΩ.
2.7~5.5V Input Voltage Range.
55µA Low Quiescent Current.
Ultra Fast Load Transient Speed.
High Switching Frequency 1.0MHz Minimizes the External Components.
Internal Soft-start Limits the Inrush Current.
Reliable Short Circuit Protection.
Output Auto Discharge Function.
RoHS Compliant and Halogen Free.
Compact Package: QFN1.5×1.5-7.
