OUT
= 3.3V, V
BATT
= 2.0V, T
A
= -40°C to +85°C. Typical values are at T
A
= +25°C, unless otherwise noted.) (Note 1)
Note 1: Specifications to -40°C are guaranteed by design and not production tested.
Note 2: Supply current into OUT. This current is drawn from the source battery, but is reduced in value according to the step-up
ratio and efficiency.
Note 3: Does not include switching losses and output quiescent current. See the Input Current and Output Voltage vs. Input Voltage
(On, 330Ω) graph in the Typical Operating Characteristics for operating quiescent current.
