Part Number: LM2831 Other Parts Discussed in Thread: TPS628512 , TPS628302 Tool/software: Hi
I recently downloaded failure rate information for LM2831YMFXNOPB.
As there are limited devices on lifetest, the failure rate is estimated as 6.4FIT.
Do you have…

Hello E2E,
Based on Figure 29, the LM2831Z has a 3MHz switching frequency but the inductor suggested only supports up to 100kHz, will this work? Also, for inductor selection, please share the formula for this: 1. inductor value 2. frequency…
Part Number: LM2831 Hi,
By adding land pattern of capacitor between Vout and FB, can his board adjust phase margin? My customer plans to add land pattern of capacitor to adjust the phase margin. If phase margin is failed on his actual board, he wants to…
Part Number: LM2831 Other Parts Discussed in Thread: TPS62825 , TLV62569 Our board is powered by 5V.
3.3V is provided by local switching DC-DC converter LM2831YMF usually works well, but it doesn't work well when very short SAG (short time power cut) was…
Part Number: LM2831 Hi Team,
We have a customer using LM2831YSD/NOPB for a 5VDC to 1.5VDC converter with a maximum output current of 80mA. Under certain conditions (mostly low temperatures) the output voltage is very noisy. He has simulated the design using…
Part Number: LM2831 Other Parts Discussed in Thread: ADS8528 , TLV62565 , LMR10515 Hello,
We have been having FPGA I/Os go bad and we think it might be caused by the 3.3V LM2831 regulator supplying power to it. The maximum FPGA's maximum allowed I/O power…
Thank you for your comments,
Also, can you please review the below schematics?
I have used LM2831 regulator for powering DDR3 and VTT VREF termination regulator LP2998 and For LM2831 given input is 3.3V and required output is 1.5V@400mA, I have given…
Part Number: LM2831 Hi TI expert,
My customer original designed ST1S06A for their project, we proposed our solution --- LM2831 but not p2p compatible.
May I know can we co-layout with ST1S06A? It's very import for us that can convince our customer to implement…
Part Number: LM2831 Hi team,
Can I clarify the meaning of the enable threshold? The datasheet says Shutdown Vth = 0.4Vmax, and Enable Vth = 1.8Vmin. For that description, will the device be enabled or disabled between 0.4V - 1.8V, it means "undefined…
