Part Number: LM25143-Q1 Other Parts Discussed in Thread: LM5143-Q1 , LM5143 , LM25143 , LM5143-Q1EVM-2100 Hi team,
I have some questions here.
1. LM25143-Q1 can be designed as spec LM25143-Q1?
2. Since this part number is discrete solution and no EVM. if…
Part Number: LM25143-Q1 Hi TI expert,
May I know whether the ENx can be controlled separately under single output - dual phase structure?
We have to connect the mode/FBx/SSx pins accordingly but wondering whether we can pull low EN2 only in order to…
Part Number: LM25143-Q1 Hi team,
The datasheet of LM25143-Q1 shows hiccup mode timing diagram in Fig. 9.6. If the timing chart includes Vout, Iout, and Iout(CL), it's easy for my customer to understand the HICCUP mode behaver.
Could you show the timing…
Other Parts Discussed in Thread: LM25143-Q1 , LM25143 Our project design uses an LM25143-Q1 as the primary power supply, providing two 5V outputs for the secondary PMIC. FB1 and FB2 are connected to AGND and operated in DCM mode. The soft-start time is set…
Part Number: LM25143-Q1 The followings are question for LM25143-Q1 from a customer.
1. データーシートの図9.9のようなインターリーブで 3.3V出力の仕様をWebenchで回路生成させるとVCCXはGND接続となります。 一方、図9.9(DS_P33)でのVCCXはVout(3.3V)に接続されています。この違いは何が原因ですか？ If you generate a simulation bench circuit…
Part Number: LM25143-Q1 Other Parts Discussed in Thread: LM5143 dear
customer use LM25143-Q1，and want to design 100A circuit，but it only shows 50A in datasheet ，is it use 2pcs LM25143-Q1 to push 100A?thanks in advance
Part Number: LM25143-Q1 Hello A sample PCB with Vout1: 12.5 V 30A, Vout2: 8V, and 12A output was manufactured using LM25143-Q1. However, the current output is not working properly, so please review the circuit diagram. Is it possible to request a circuit…
Part Number: LM25143-Q1 Hi team,
What is the Iq if configurate 25143 as two phase single output?
VOUT1=VOUT2=3.3V, DEMB=GND, MODE=VDDA
VOUT1 and VOUT2 are both enabled. I see in datasheet we only have Iq data in one enabled channel.
Thanks!
Part Number: LM25143-Q1 Hi team,
How to calculate or derive input impedance of a LM25143-Q1 circuit? It is used to design the input filter before the power supply.
In the below app note: The Middlebrook’s extra element theorem (paper [2]), explains that…
Part Number: LM25143-Q1 Other Parts Discussed in Thread: LM25143 Hi team,
Is it possible to operate LM25143 with 3 phase and have one of the secondary IC’s output separated?
We want independent control to have 2 output with same voltage level Is…
