SY8008A/SY8008B/SY8008C
High Efficiency 1.5MHz, 0.6A/1A/1.2A
Synchronous Step Down Regulator
Preliminary Spec
General Description
The SY8008A, SY8008B and SY8008C are high-
efficiency 1.5MHz synchronous step-down DC-DC
regulator ICs capable of delivering up to 1.2A output
currents. The SY8008 family 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.
Low output voltage ripple and small external inductor
and capacitor sizes are achieved with 1.5MHz
switching frequency. This along with small SOT-
23/TSOT-23 footprint provides small PCB area
application.
Applications
• Portable Navigation Device
• Smart phone
• USB Dongle
• Set Top Box
• Media Player
Features
• low Rds(on) for internal switches (top/bottom)
ο SY8008A: 300m Ω /250m Ω, 0.6A
ο SY8008B: 250m Ω /200m Ω, 1A
ο SY8008C: 200m Ω /150m Ω, 1.2A
• 2.5-5.5V input voltage range
• 1.5MHz switching frequency minimizes the
external components
• Internal softstart limits the inrush current
• 100% dropout operation
• RoHS Compliant and Halogen Free
• Compact package: SOT23-5/ TSOT23-5 pin
