Description
General part information
LT8610ALT8610AB Series
The LT8610A/LT8610AB series are compact, high efficiency, high speed synchronous monolithic step-down switching regulators that consume only 2.5μA of quiescent current. Compared to the LT8610, they have higher maximum output currents of 3.5A and a faster minimum switch-on time of 30ns. The LT8610A has the same low ripple burst mode performance of the LT8610, while the LT8610AB has even higher light load efficiency.The other features of the LT8610 remain unchanged in the LT8610A/LT8610AB series. A SYNC pin allows synchronization to an external clock. The EN/UV pin has an accurate 1V threshold for VINundervoltage lockout or shut down. A capacitor on the TR/SS pin programs the output voltage ramp rate during startup. The PG flag signals when VOUTis within ±9% of the programmed output voltage as well as fault conditions.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
