FIGURE 2 – MAXIMUM POWER vs CASE TEMPERATURE

The maximum Power dissipation is limited by the thermal shutdown function of each regulator chip in the VRG8601/02. The

graph above represents the achievable power before the chip shuts down. The first line in the graph represents the maximum

power dissipation of the VRG8601/02 with one regulator on (the other off) and the other line represents both regulators on

dissipating equal power. If both regulators are on and one regulator is dissipating more power that the other, the maximum power

dissipation of the VRG8601/02 will fall between the two lines. This graph is based on the maximum junction temperature of

150°C and a thermal resistance (

JC) of 5°C/W.
