The LT8609EMSE#PBF is a compact, high efficiency, high speed synchronous monolithic step-down Switching Regulator that consumes only 1.7μA of quiescent current. The LT8609 can deliver 2A of continuous current with peak loads of 3A (<1sec) to support applications such as GSM transceivers which require high transient loads. Top and bottom power switches are included with all necessary circuitry to minimize the need for external components. Low ripple burst mode operation enables high efficiency down to very low output currents while keeping the output ripple below 10mV. A SYNC pin allows synchronization to an external clock or spread spectrum modulation of switching frequencies for low EMI operation. Internal compensation with peak current mode topology allows the use of small inductors and results in fast transient response and good loop stability.
