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 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!
