Calculating Power Loss and SOA for Different Operating Conditions
To calculate Power Loss for a given set of operation conditions, the following procedure should be
followed:
Power Loss Procedure
1. Determine the maximum current and obtain the maximum power loss from figure 1
2. Use the normalized curves to obtain power loss values that match the operating conditions in
the application
3. The maximum power loss under the application conditions is then the product of the power
loss from figure 1and the normalized values.
To calculate the Safe Operating Area (SOA) for a given set of operating conditions, the following
procedure should be followed:
SOA Procedure
1. Determine the maximum PCB and CASE temperature at the maximum operating current for
each iP2005C
2. Use the normalized curves to obtain SOA temperature adjustments that match the operating
conditions in the application
3. Then, add the sum of the SOA temperature adjustments to the T X axis intercept in figure 2
Design Example
Operating Conditions :
Output Current = 30A
Switching Freq = 750 kHz
Input Voltage = 10V
Inductor = 0.2μH
Output Voltage = 1.3V
Drive Voltage (VDD) = 5V
Calculating Maximum Power Loss:
(Figure 1) Maximum power loss = 7.0W
(Figure 3) Normalized power loss for input voltage ≈ 0.975
(Figure 5) Normalized power loss for output inductor ≈ 1.012
(Figure 6) Normalized power loss for switch frequency ≈ 0.88
Calculated Maximum Power Loss ≈ 7.0W x 0.975 x 1.0 x 1.012 x 0.88 ≈ 6.09W
