SY8089A1 - 2A Synchronous Step Down Regulator

Datasheet Summary

Description

SY8089A1 is a high efficiency 1.5MHz synchronous step down DC/DC regulator capable of delivering up to 2A output current.

It can operate over a wide input voltage range from 2.5V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

Features

2.5V to 5.5V Input Voltage Range.
50μA Low Quiescent Current.
Low RDS(ON) for Internal Switches (Top/Bottom) 130mΩ /85mΩ.
High Switching Frequency 1.5MHz Minimizes the External Components.
Internal Soft-start Limits the Inrush Current.
100% Dropout Operation.
Hic-cup for Short Circuit Protection.
Output Auto Discharge Function.
RoHS Compliant and Halogen Free.
Compact Package: SOT23-5.
