Part Number: PMP21278 Hello team,
I received a question from my customer about Buck/boost controller. I would appreciate if you could give us some advice about it.
The customer is willing to use a buck/boost controller for their system and thought that…
Part Number: LM5176 Other Parts Discussed in Thread: PMP21278 , , PMP , CSD19502Q5B Hi Ti Team
The power Loss of PMP21278 300W Buck-Boost Eval board for Vin=50, full Load is equal 25W
and power Loss of for Vin=12, full Load is equal 10W.
On the other hands…

Part Number: CSD88599Q5DC Other Parts Discussed in Thread: PMP21278 , Hi team,
My customer is thinking of implementing this reference design in their system, but the FETs are pretty pricey.
Can the above FET module replace the four FETs on the input stage…
Hi Brian,
LM5176-Q1 do not have a specified max output current.
Generally, the max output current is limited by
the gate driver strength (2A for LM5176-Q1)
voltage stress of SW pins (-5~65V for 20ns transient).
We have 12V/25A a reference design similar…
Hello Shuai,
That's a very large range for Vin and Vout.
I found a reference design for for a 4-switch buck-boost that is very close to those requirements: PMP21278 .
Vin = 9V to 50V, Vout = 12V, Iout = 25A.
There is also a design for USB-C at 20V…
Part Number: LM5176-Q1 Other Parts Discussed in Thread: PMP21278 Hello Team,
My customer started to evaluate LM5176-Q1 for super capacitor charging application after built their proto board based on our PMP21278 reference design and their schematic is almost…
Hello Gareth,
Do you mean that this voltage drop happens even with no load attached to the output?
The capacitor calculation in the tool gives a start point, but a calculation tool is not able to finalize a system. Therefore I recommend to check the transition…
Hi Youhao,
We tested again using the same inductor as that was used in this reference design PMP21278
XAL1580-202ME spec as below
Below is our test result, at 25A the circuit still not work correctly, however if load is 1A it work OK.
May we have your…
