The LM2655MTCX-3.3 is a high-efficiency synchronous step-down switching regulator capable of delivering up to 2.5A output current. It operates within an input voltage range of 4V to 14V and achieves efficiencies exceeding 90%, with a maximum efficiency of 96%. The device features an internal high-side MOSFET with a low ON-resistance of 33m,Ѷ, which contributes to its high power density and compact TSSOP-16 package. This regulator supports both synchronous and asynchronous operation modes, allowing designers to optimize for efficiency or cost. It includes integrated current sensing circuitry, eliminating the need for external current sensing resistors. Additional features include programmable soft-start, input undervoltage lockout, output overvoltage and undervoltage protection, and thermal shutdown capabilities. The LM2655MTCX-3.3 is suitable for applications such as hard disk drives, internet appliances, TFT monitors, and battery-powered devices.
