LTC3335_15 Datasheet, PDF (3/28 Pages) Linear Technology – Nanopower Buck-Boost DC/DC with Integrated Coulomb Counter

LTC3335
Electrical Characteristics The l denotes the specifications which apply over the full operating junction
temperature range, otherwise specifications are at T_A = 25°C (Note 2). BAT = PBAT = 3.6V, GNDA = GNDD = PGND = 0V, V_OUT = PV_OUT.
