Description
General part information
LT8610ACLT8610AC-1 Series
The LT8610AC/LT8610AC-1 is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that consumes only 2.5μA of quiescent current. Compared to the LT8610AB, the LT8610AC/LT8610AC-1 has a lower feedback voltage of 800mV and a lower minimum VINof 3V. The LT8610AC/LT8610AC-1 has the same additional features of the LT8610AB as compared to the LT8610: higher maximum output current of 3.5A, faster minimum on time of 30ns, and higher light load efficiency.The LT8610AC/LT8610AC-1 has a SYNC pin for synchronization to an external clock. A capacitor on the TR/SS pin programs the output voltage ramp rate during startup. The PG flag signals when VOUTis within ±8% of the programmed output voltage as well as fault conditions. The LT8610AC-1 has internal compensation optimized for high switching frequencies resulting in improved transient response compared to the LT8610AC. The LT8610AC-1 also has a feature which will soft-start the part when exiting dropout or brownout conditions reducing output voltage overshoot.Feedback VoltageMin VINOutput CurrentNotesLT8610AC-10.80V3.0V3.5AFSW= 1.5MHz to 2.2MHz, Optimized Transient ResponseLT8610AC0.80V3.0V3.5AFSW= 200kHz to 2.2MHzLT8610AB0.97V3.4V3.5AImproved Burst Mode EfficiencyLT8610AX0.97V3.4V3.5A175°C Max Junction TempLT8610A0.97V3.4V3.5AHigher IOUT, 30ns Min On TimeLT86100.97V3.4V2.5A-ApplicationsAutomotive and Industrial SuppliesGSM Power Supplies
