1 / 11 page TS3552 2A/350kHz Synchronous Buck DC/DC Converter 1/11 Version: B11 SOP-8 General Description The TS3552 is a synchronous step-down DC/DC converter that provides wide 4.75V to 23V input voltage range and 2A continuous load current capability. Fault protection includes cycle-by-cycle current limit, input UVLO, output over voltage protection and thermal shutdown. Besides, adjustable soft-start function prevents inrush current at turn-on. This device uses current mode control scheme that provides fast transient response. In shutdown mode, the regulator draws 1µA or less of supply current. Features ● Operating Voltage Range 4.75V~23V ● Output load current up to 2A ● High Efficiency: Up to 93% ● Fixed Switching Frequency 350kHz ● 100m Internal Power MOSFET ● Adjustable Output Voltage from 0.925~20V ● Stable with Low ESR Output Ceramic Capacitors ● Current Mode Operation ● Input Under Voltage Lockout ● Over Temperature Protection ● Cycle-by Cycle Current limit ● <1µA Shutdown Current Ordering Information Part No. Package Packing TS3552CS RLG SOP-8 2.5Kpcs / 13” Reel Note: “G” denote for Halogen Free Product Application ● Set-Top-Box ● DVD, LCD Displays ● Netbook ● Distributed Power System ● DSL Modems Typical Application Circuit 3.3V Output Application Circuit Pin Definition: 1.
