DESCRIPTION:
The SY3167 is a monolithIC step-down switchmode converter with a built in internal powerMOSFET. It achieves 2A continuous output currentover a wide input supply range with excellentload and line regulation.The SY3167 requires a minimum number ofreadily available standard external components.Current mode operation provides fast transientresponse and eases loop stabilization.
Fault condition protection includes cycle-bycyclecurrent limiting and thermal shutdown. In shutdown mode the regulator draws 25μA of supply current.
FEATURES:
◆ 2A Output Current
◆ 0.22Ω Internal Power MOSFET Switch
◆ Stable with Low ESR Output Ceramic Capacitors
◆ Up to 95% Efficiency
◆ 25μA Shutdown Mode
◆ Fixed 450KHz Frequency
◆ Thermal Shutdown
◆ Cycle-by-Cycle Over Current Protection
◆ Wide 4.75 to 25V Operating Input Range
◆ Output Adjustable from 1.22V to 21V
◆ Programmable Under Voltage Lockout
