Part Number: LM5122-Q1 HI,
The datasheet states: "Minimum VIN operating voltage is always 4.5V. The minimum input power supply voltage can be 3V after start-up, assuming VIN voltage is supplied from an available external source."
1.Am I correct in…
Part Number: LM5122-Q1 Other Parts Discussed in Thread: LM5122 , LM5085 I implemented a solution using LM5122 to boost Votlage from 12V to 50V. The solution proposed by WeBench was implemented:

This solution is unstable when…
Part Number: LM5122-Q1 Tool/software: Hello：
The above is the schematic diagram, and the following issues were encountered during use:
1. HO output waveform is very messy and not working properly
2. Without using HO to drive MOS synchronization…
Part Number: LM5122-Q1 Other Parts Discussed in Thread: LM5122EVM-1PH , Dear
We would like to use the LM5122-Q1 in our application development. For design reference, could you provide the design files (schematic, PCB layout) of the LM5122EVM-1PH?

Part Number: LM5122-Q1 Other Parts Discussed in Thread: LM5122 Tool/software: Hi Team,
I’ve designed a 2-phase interleaved boost converter using the LM5122QMHX/NOPB . Input: 12V Output: 36V @ 6A to 8A (no load during testing)
I'm facing a strange…
Part Number: LM5122-Q1 Other Parts Discussed in Thread: PMP , LM46002-Q1 , LM5122 Hello, I have come across a legacy design which boost from -42 to -28 volts, using a switching frequency of 30kHz (base on the resistance selected and the formulae on the…
Part Number: LM5122-Q1 Other Parts Discussed in Thread: LM5122 Tool/software: Hi, I am currently working on a design I created using Webench Power Designer am finding that my FET and the LM5122 is not surviving. It looks like the SW pin is sinking too…
Part Number: LM5122-Q1 Other Parts Discussed in Thread: LM5122 Tool/software: Hi,
we want to use the LM5122 as a SEPIC controller. We have a mock up that works but we want to use the current cycle-by-cycle protection as a short-circuit protection. …
