Part Number: LV2862 HI, We have made a custom board with LV2862 with 33uH inductor and DLFS1100 etc. We have device heating up badly and goes to thermal shut down. If we power the device with 24V (output is 12V) it works well but still heats to around 45…
Hi Shirin,
Schematic-wise, there doesn't seem to be anything too strange. From how I see it, there are two sitautions.
1) More difficult, but if LV2862 is required, you may try increasing your inductor value and output cap. Even at 20mA, it looks…
Hi Ridge,
I replaced the B130LAW schottky with a SS14 which has lower leakage current at higher temperatures, and that seemed to solve the problem. So the schottky is definitely the trigger, but it still does not explain what the LV2862 is doing and how…
Part Number: LV2862
I'm using an LV2862 to step down 22V to 3.3V, powering a MCU.
During initial MCU programming, the 3.3V rail may be supplied by the programming jig, while the rest of the device is unpowered.
This would back feed the LV2862 with…
Part Number: LV2862 Other Parts Discussed in Thread: LMR36006 , Hi,
I would like to use the Y version as a power source to my circuit (input voltage could be from 9-36V) with the following conditions:
Over sleep mode - the DC-DC should supply power of…
Part Number: LV2862 Hi,
I have a requirement to drive a Triac from the MCU powered by the LV2862. The AC supply is typ 24Vac @ Rc terminal with respect to C terminal. The Triac is driven as follows. The MCU GND is always regulated at Rc - 3V3. Basically…
Part Number: LV2862 Hello
I traced the detailed design procedure in t the LV2862 datasheet page11.
however, I could not get the same result of it.
I used all neccesary parameter values below.
Vin_max = 16
Vout = 5
Io_max = 0.6
KIND = 0.4
fsw = 770000

Part Number: LV2862 Other Parts Discussed in Thread: LMR51606 Hi,
I have tried our first prototypes and output seems to be regulating well for our load which is a average load of ~7mA with peak loads of ~18mA for a duration of ~10ms.
We use the 770kHz…
