The LT8609SIV#PBF is a compact, high-efficiency, high-speed synchronous monolithic step-down switching regulator from Analog Devices. It consumes only 1.7µA of non-switching quiescent current and can deliver 2A of continuous current with peak loads of 3A. This regulator features a wide input voltage range from 3.0V to 42V and operates with a switching frequency adjustable from 200kHz to 2.2MHz.
Key features include low ripple Burst Mode operation for high efficiency at low output currents, with output ripple below 10mV P-P. It supports synchronization to an external clock or spread spectrum modulation for low EMI operation. Internal compensation and peak current mode topology allow for the use of small inductors and provide fast transient response.
The LT8609SIV#PBF is available in a small 16-lead 3mm x 3mm LQFN package, suitable for surface mount applications. The EN/UV pin has an accurate 1V threshold for programming VIN undervoltage lockout or shutdown, reducing input supply current to 1µA. A PG flag signals when VOUT is within ±8.5% of the programmed output voltage, as well as fault conditions.
This device is well-suited for applications requiring high efficiency, low quiescent current, and compact size, such as general-purpose step-down and low EMI step-down designs.
