iP1202PbF Power Block
The iP1202PbF is a fully optimized solution for medium current synchronous buck applications requiring up to
15A or 30A. The iP1202PbF is optimized for 2 phase single output applications up to 30A or dual output, each
up to 15A with interleaved input. It includes full function PWM control, with optimized power semiconductor chip-
sets and associated passives, achieving high power density. Very few external components are required to
create a complete synchronous buck power supply.
iPOWIR technology offers designers an innovative space-saving solution for applications requiring high power
densities. iPOWIR technology eases design for applications where component integration offers benefits in
performance and functionality. iPOWIR technology solutions are also optimized internally for layout, heat
transfer and component selection.

* Although, all of the difficult PCB layout and bypassing issues have been addressed with the internal design of the iPOWIR block, proper layout techniques
should be applied for the design of the power supply board. The iPOWIR block will function normally, but not optimally without any additional input decoupling
capacitors. Input decoupling capacitors should be added at Vin pin for stable and reliable long term operation. See layout guidelines in datasheet for more
detailed information.

Applying the Safe Operating Area (SOA) Curve
www.datasheet4u.com
The SOA graph incorporates power loss and thermal resistance information in a way that allows one to solve for maximum
current capability in a simplified graphical manner. It incorporates the ability to solve thermal problems where heat is drawn
out through the printed circuit board and the top of the case.
Cas e Te m pe ratur e (ž8Ã
Procedure
1) Draw a line from Case Temp axis at TCASE to the PCB
Temp axis at TPCB.
2) Draw a vertical line from the TX axis intercept to the SOA
curve. (see AN-1047 for further explanation of TX )
3) Draw a horizontal line from the intersection of the vertical
line with the SOA curve to the Y axis. The point at which
the horizontal line meets the y-axis is the SOA current.
4) If no top sided heatsinking is available, assume TCASE
temperature of 125°C for worst case performance.

Adjusting the Power Loss and SOA curves for different operating conditions
To make adjustments to the power loss curves in Fig. 2, multiply the normalized value obtained from the curves in Figs. 4,
5, 6 or 7 by the value indicated on the power loss curve in Fig. 2. Remember that the power loss in Fig 2. is the power loss
for 2 outputs operating with the same output voltage. If differing output voltages are used the initial power loss for each
channel needs to be divided by 2. Then if multiple adjustments are required, multiply all of the normalized values together,
then multiply that product by the value indicated on the power loss curve in Fig. 2. The resulting product is the final power
loss based on all factors. See example no. 1.
To make adjustments to the SOA curve in Fig. 3, determine your maximum PCB Temp & Case Temp at the maximum
operating current of each iP1202PbF. Then, add the correction temperature from the normalized curves in Figs. 4, 5, 6 or
7 to the TX axis intercept (see procedure no. 2 above) in Fig. 3. When multiple adjustments are required, add all of the
temperatures together, then add the sum to the TX axis intercept in Fig. 3. See example no. 2.
Operating Conditions for the following examples:
Output1
Output Current = 12A
Output Voltage = 1.2V
Input Voltage = 8V
Sw Freq= 300kHz
Inductor = 1.75µH
Output2
Output Current = 10A
Output Voltage = 3.3V
Input Voltage =8V
Sw Freq= 300kHz
Inductor = 1.75µH
Example 1) Adjusting for Maximum Power Loss:
Output1 (Fig. 2) Maximum power loss = W 8.25/2 = 4.125W
(Fig. 4) Normalized power loss for input voltage 0.93
(Fig. 5) Normalized power loss for output voltage 0.98
(Fig. 6) Normalized power loss for frequency 1.0
(Fig. 7) Normalized power loss for inductor value 0.98
Adjusted Power Loss = 4.125 x 0.93 x 0.98 x 1.0 x 0.98 3.7W
