Hi team,
Customer's requirements are: Vin=12V(13V Max, 11V Min) Vout=3.3V/60A. Could you please help to design a circuit?

Hi Rannie
1. you can use the Power fusion Gui in off-line mode to select the pin strap in pin strap tab
2. you can also use the excel calculator for designing which i am attaching here and also use the pin strap tab to select thr pin strap table
a.In device calculator tab input cell E127 (CZI value) and cell E129 (CPI value) manually from cells F97 (CZI calculated value) and F98 (CPI calculated value) to update the frequency curves
3. or you can select and calculate the pin strap as mentioned in the data sheet
for frequency
first select the Resistor Divider code for required Freq
after selecting the resistor divider code see if selected resistor divider is no divide, even divider or divider based on that choose the Resistor to Ground code
once you have both the codes for resistor divider and resistor to ground use the look up table on the datasheet for resistor values
Thank you

Hi Savith,
ctm is testing on EVM and found the Tmax is 80C.
The test condition is:
Their requirement on thermal is do not exceed 50C with the fan. The fan spec on ctm's board is 0.5m^3/min(max), 17.1LFM. The Load ctm need is 60A.
So, could you please give some suggestion to optimize the thermal performance?

Hi Calan,
ctm is wanting for our response to determine whether using this device. So please help to reply ASAP.

HI Rannie
what is the temp when there is a airflow? is it with heat sink ?
Thank you
Savith
Rannie,
A heat sink will help, as will ducting the fan's airflow so that 0.5m^3min will produce a lot more linear flow
0.5m^3/min is 17.7 Cubic Feet per Minute (CFM) how many LFM that is depends on the cross area, of your duct that into.
A 3 inch x 3 inch path, with 17.7 CFM is 283LFM
LFM=CFM/(cross sectional area)
Thank you
Savith
Heat sink is limited by the size and volume. Fan is also fixed. Is there any other method?
