Part Number: LM27402 Hi Team,
I have 2 questions when using LM27402.
Q1: Datasheet says the minimum voltage on LG can't exceed -0.3V, while both customer board and EVM show around -1V (period 4ns) at the beginning of turning on Low Side FET as below.…
Part Number: LM27402 Hi,
We are facing issue with LM27402 switching regulator for 1V @ 14A output from 12V input. During startup itself regulator is going into OCP hiccup mode and its continue in that. Final load to this regulator will be around 10A only…
Part Number: LM27402 Tool/software: WEBENCH® Design Tools Hi, We are using the "LM27402" buck controller for converting Vin=3.3V to Vout=1V@10A. For this design, we need a soft start delay tss=5ms. For this delay, the WEBENCH is recommending to use a capacitor…

hello dear,i am looking for an led drive board.my first aim was to use lm3433 but they told me that it is no more availble to use as for LM27402 they recommend…
Part Number: LM27402 Hi all,
I have a customer who would like to use LM27402 to generate a 20V to 0.72V Buck Converter switching at 1MHz. I see a MAX duty cycle and minimum off time in the datasheet, but no minimum on time spec.
Is it possible to use…
Part Number: LM27402 Other Parts Discussed in Thread: LM27403 , HI
I having trouble using the LM27402SQ/NOPB(WQFN Type)
I built a circuit to get 12V/4A output with 19V input. but It was fail.
I used TI Webench as a reference circuit, and the information…
Part Number: LM27402 Hello,
During test LM27402 board, High side FET is broken like as shorted.
Could you check attached schematic if there is any fault?

Part Number: LM27402 The enclosed design does not start-up consistently. To change Vout from 10V to 12V, I changed R32 from 1.3K to 1.07K. When it works, Vout=12V, it just doesn't come up consistently. Do I need to change any of the other component…
Part Number: LM27402 Tool/software: WEBENCH® Design Tools Hi,
I am trying to design a DC-DC converter capable of sourcing 12A at 2.1V with a 4-13V input. My design is based on TI’s WEBENCH web app using TI’s LM27402. The output design from…
Part Number: LM27402 What is max current on LM27402 for 12Vin/9Vout ?
and Antminer S9 is using LM27402 for 12Vin/9Vout/30A, Are they using in the over-specs?
