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,
