ELECTRICAL CHARACTERISTICS

VIN=1.2V, VOUT_ON=VIN, VPROG is the programmed voltage according to S2, S1, S0 pins set for STORE voltage of 3V unless otherwise

specified. TA=-40°C to 85°C. Typical values are at TA=+25°C unless otherwise specified. Please see Note 1.

Note 1: All devices are 100% production tested at TA = +25°C and are guaranteed by characterization for TA = -40°C to +85°C, as specified.

Note 2: ISTORE(MAX) is provided as the Maximum Average STORE Current by the graph entitled “Expected Maximum STORE Output Current” in

the TS3310 Applications Section.

Note 3: VSTORE output is driven above regulation point. No switching is occurring.

Note 4: VSTORE=3V. L=100µH. CSTORE=1µF.
