denotes the specifications which apply over the specified operating

junction temperature range, otherwise specifications are at TA = 25°C (Note 2). VIN = 5V, BAT = 3.6V, SCAP = OV, LDO_IN = 0V unless

otherwise specified.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: The LTC3330E is tested under pulsed load conditions such that

TJ ≈ TA. The LTC3330E is guaranteed to meet specifications from 0°C to

85°C. The LTC3330I is guaranteed over the –40°C to 125°C operating

junction temperature range. Note that the maximum ambient temperature

consistent with these specifications is determined by specific operating

conditions in conjunction with board layout, the rated package thermal

impedance and other environmental factors.

Note 3: TJ is calculated from the ambient TA and power dissipation PD

according to the following formula: TJ = TA + (PD • θJA).

Note 4: Dynamic supply current is higher due to gate charge being

delivered at the switching frequency.
