Description
General part information
LT8615 Series
The LT®8615 is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that can deliver 3.5A of continuous current. The LT8615’s ultralow 2.5μA quiescent current in Burst Mode operation (with the output in full regulation) enables high efficiency down to very low load currents while keeping the output ripple below 10mVP-P.A SYNC pin allows synchronization to an external clock or spread-spectrum modulation 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 EN/UV pin has an accurate 1V threshold and can be used to program VINUVLO or to shut down the part. A capacitor on the TR/SS pin programs the output voltage ramp rate during start-up. An open-drain PG pin flag signals when the output is within ±8% as well as fault conditions.APPLICATIONSAutomotive and Industrial SuppliesLow EMI Step-Down
