Synchronous Step-Down Regulator With 2.5µA Quiescent Current: LT8609S

LT8609S-acl

Analog Devices offers the LT8609S compact, high efficiency, high speed synchronous monolithic step-down switching regulator designed to consume only 1.7 µA of non-switching quiescent current. The LT8609S can deliver 2A of continuous current with peak loads of 3A (<1sec) to support applications such as GSM transceivers which require high transient loads.

The LT8609S features low ripple burst mode operation for high efficiency down to very low output currents while keeping the output ripple below 10mVP-P. 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. The LT8609S is available in a small 16-lead 3mm × 3mm LQFN package.
