SX2106

SX2106 85T 21V, 2 A, 600KHz Synchronous Step- Down DC/DC Converter 85T Features Description The SX2106 is a synchronous step -down DC/DC converter that provides wide 4.5V to 21V input voltage range and 2A continuous load current capability. The SX2106 fault protection includes cycle -by-cycle current limit, UVLO, output overvoltage protection and thermal shutdown. The adjustable soft-start function prevents inrush current at turn-on. This device uses current mode control scheme which provides fast transient response. Internal Compensation function reduces external compensation components and simplifies the design process. In shutdown mode, the supply current is less than 1μA. The SX2106 is available in a SOT-23-6 package, provides good thermal conductance. ● High Efficiency up to 94% ● Low Rds(on) Integrated Power MOSFET ● Internal Compensation Function ● Wide Input Voltage Range: 4.5V to 21V ● Adjustable Output Voltage from 0.8V to 17.85V ● 2A Output Current ● Fixed 600KHz Switching Frequency ● Current Mode Operation ● Cycle-by-Cycle Current Limit ● Over-Temperature Protection with Auto Recovery ● Output Overvoltage Protection ● Under Voltage Lockout ●
