Other Parts Discussed in Thread: LM61480
Is it possible to double the current capacity by bundling the two outputs of TPS5450?
Many LEDs have a common Anode, which requires a large current.
Please give me advice.

Postscript.
The TPS5450 datasheet states that the maximum output current of the DCDC circuit is 5A, but we would like to use it in a configuration where two DCDC circuits are connected in parallel because we need a load current of 6A/7V.
The circuit is shown below.
Hi Shinji-Ota,
This is not an efficient solution and I do not recommend tying together the outputs for this device because of conflicting beat frequencies in the output ripple. We do offer some higher IOUT capable devices, like LM61480 which can provide a smaller solution size and meet your load requirements.
