SLUS606N – JUNE 2004 – REVISED NOVEMBER 2008 TA < 40°C DERATING FACTOR PACKAGE θ JA θ JC POWER RATING ABOVE TA = 40°C RHL(1) 46.87°C/W 2.5°C/W 1.81 W 0.021 W/°C (1) This data is based on using the JEDEC High-K board, and the exposed die pad is connected to a copper pad on the board. This is connected to the ground plane by a 2x3 via matrix. MIN NOM MAX UNIT Supply voltage, VCC and IN (Tie together) 4.35(1) 16(2) V Operating junction temperature range, TJ –40 125 °C (1) The IC continues to operate below Vmin, to 3.5 V, but the specifications are not tested and not specified. (2) The inherent switching noise voltage spikes should not exceed the absolute maximum rating on either the IN or OUT pins. A tight layout minimizes switching noise.
