Applications Note: AN_SY8805A
High Efficiency 1 MHz, 5A
Synchronous Step Down Regulator
General Description
The SY8805A is a high-efficiency 1 MHz synchronous
step-down DC-DC regulator, Current Mode Control IC
capable of delivering up to 5A output current. The
SY8805A operates over a wide input voltage range
from 3V to 5.5V. It integrates main switch and
synchronous switch with very low RDS(ON) to minimize
the conduction loss. High intergrated solution and
DFN2x2-8 package perform the optimized BOM cost
and reduce external component part count. Low input
and output voltage ripple, small external inductor and
capacitor sizes, small PCB layout space are achived
with 1MHz switching frequency.
