SYR827

High Efficiency 5.5V, 6A, 2.4MHz

I²C Programmable, Synchronous Step Down Regulator

Preliminary Specification

General Description

Features

SYR827 is a high efficiency 2.4MHz synchronous step

down DC/DC regulator IC capable of delivering up to 6A

output currents. It can operate over a wide input voltage

range from 2.6V to 5.5V and integrate main switch and

synchronous switch with very low R_{DS (ON)}to minimize the

conduction loss. The output voltage can be programmed

from 0.7125V to 1.5V through I²C interface.

•

Input voltage range: 2.6V to 5.5V

2.4 MHz switching frequency minimizes the external

components

•

Typical 65uA quiescent current

Low R_DS(ON)for internal switches (PFET/NFET):

28mΩ/17mΩ

•

Programmable Output Voltage: 0.7125V to 1.5V in

12.5mV steps

SYR827 is in a space saving, low profile CSP1.56*1.96-20

package.

•

6A continuous output current capability.

Capable for 0.25uH inductor and 22uF Ceramic

Capacitor.

Ordering Information

•

Hic-cup mode protection for hard short condition

RoHS Compliant and Halogen Free
