Hi,
1) All caps used are ceramic only at output side rated with 50V, however Vout is 5V
2) Attached the quickstart

Part Number: TPS40170 Other Parts Discussed in Thread: LM25145 , LM5146 , LM5145 Hi Team,
We would like to know the difference between TPS40170 and TPS40171.
We understand that both devices are same spec and function.
Is my understanding correct…
Part Number: LM5116 Other Parts Discussed in Thread: UCC27714 , , LM5146 Dear Expert
Our operation condition is : Input 73~80VDC, output 71.5/20A.
At present, there are some problems with insufficient driver of LM5116. Totem pole was added before…
Part Number: LM5145-Q1 Other Parts Discussed in Thread: LM5145 , LM5146 Hello,
I have a 5V power supply design that i have made as per the attached schematic but for some reason it does not work as it is supposed to. Instead of getting 5V i end with…
Part Number: LM5141 Other Parts Discussed in Thread: LM5146 I am working on a project using the LM5141 as the controller which feeds HO/HOL and LO/LOL to two gate drivers that drive two mosfets each. At first I was thinking that I need both gate drivers…
Part Number: LM5145 Other Parts Discussed in Thread: LM5146 , Hello,
I'm working on a project of building a current profile generator using the LM5145 IC to do the DC/DC conversion from a battery voltage source of 48V to varied output from 3V3/5V-20A…
Other Parts Discussed in Thread: TPS61088 , LM5146 , LM5145 , LM5117 Hi Team,
My customer is looking for single chip solution to reference design PMP9806.
The expectation from the IC is When the output current is higher than the specified level, it…
HI Matt,
The VCC current calculation should take the MOSFET Qg be at the applicable VCC voltage, i.e. 7.4V unless VCCX is driven externally. Ivcc = Qg*Fsw for each FET, and then add the controller consumption (see EC table in the datasheet for that…
Hi Andrew,
Correct, both the LM5143 and LM5148 have a VCC of 5V, so the gate drive is suitable for logic-level FETs with Rdson rated for Vgs = 4.5V. The latest automotive-grade FETs from Onsemi and Infineon at 80V are logic-level devices (these typically…
