LTC3560ES6#TRPBF

LTC3560 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. Supply current during operation is only 16μA, dropping to 1μA in shutdown. The 2.5V to 5.5V input voltage range makes the device ideally suited for single Li-Ion/Li-polymer battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. Switching frequency is internally set at 2.25MHz, allowing the use of small surface mount inductors and capacitors. For noise sensitive applications the device can be externally synchronized from 1MHz to 3MHz. Burst Mode operation is inhibited during synchronization or when the SYNC/MODE pin is pulled high, preventing low frequency ripple from interfering with audio circuitry. It is used in application such as cellular telephones, wireless and DSL modems, digital still cameras, media players, portable instruments etc.
