SY8133 Datasheet | Silergy

High Efficiency 400KHz, 3A,16V Input Synchronous Step Down Regulator Preliminary SPECIFICATION General Description The SY8133 is a high efficiency 400 KHz synchronous step-down DC-DC converters capable of delivering 3A output current. SY8133 operates over a wide input voltage range from 4V to 15V 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 400KHz switching frequency. Applications - Set Top Box - Portable TV - Access Point Router - DSL Modem - LCD TV Features - low Rds(on) for internal switches (top/bottom) 120/80 mΩ, - 4-15V input voltage range - 400KHz switching frequency - Internal softstart limits the inrush current - 2% 0.6V reference - Ro HS pliant and Halogen Free - pact package: SO8 with exposed paddle Ordering Information SY8133- (- - )- Temperature Code C: -40°C~85°C Package Code: FC: SO8E Spec Code Typical Applications VIN CIN IN BS LX VOUT GND FB R1 COUT R2 Figure...
