Maximum power dissipation is a function of TJ(max), θJA and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = [TJ(max)–TA] / θJA.
(2)
This thermal data is measured with high-K board (4-layer board according to JESD51-7 JEDEC standard).
ELECTRICAL CHARACTERISTICS
Minimum and maximum values are at VI = 2.3V to 5.5V, VO = 1.8V, EN = 1.8V, AUTO mode and TA = –40°C to 85°C; Circuit
of Parameter Measurement Information section (unless otherwise noted). Typical values are at VI = 3.6V, VO = 1.8V, EN =
1.8V, AUTO mode and TA = 25°C (unless otherwise noted).
