SYR828
High Efficiency 5.5V, 6A, 2.4MHz
I C Programmable, Synchronous Step Down Regulator
2
Preliminary Specification
General Description
SYR828 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 I
2
C interface.
SYR828 is in a space saving, low profile CSP1.56*1.96-20
package.
