Part Number: LM46000 Hi! I have been using the LM46000 in combination with LM2991S for a long time, but it's only recently that I have discovered an issue that I cannot explain.
The design consists of the LM46000 in inverting configuration to generate…
Part Number: LM46000 Hello,
My customer is investigating LM46000 behavior in some abnormal cases.
1)
When SYNC pin (#6) is open, what happens?
2)
When AGND pin (#10) is open, what happens?
3)
When both PGND pins (#15 and #16) are…
Part Number: LM46000 Other Parts Discussed in Thread: LM46001 Hi,
Do we have T case(max) spec of LM46000 & LM46001?
I can only find Tjunction in datasheet.
Part Number: LM46000 Hi team,
This is FAE Michael. I have 3 LM46000 EVM. But they all can't power up... I only connect the input Vin and Gnd to the power supply 12V, without any load. But the output is charging slowerly from 0.3---1.2V. Because the…
Part Number: LM46000 Hello All
As described in the title. When I have attached a resistive load of ca. 20R and I start increasing the input voltage from 0V the output is in hiccup mode until the input voltage reaches about 30V. The goal is that the…
Part Number: LM46000-Q1 Other Parts Discussed in Thread: SN6501-Q1 1. For the life requirement of energy storage project, the equivalent duration of high temperature working test under working conditions shall be higher than 105 ℃, 10701h or 125 ℃, 5508h…
Hi Jeffrey,
For LM46000 section:
Add 22uF 50V Electrolytic cap parallel with C83
C102 is option, reserve position
Add 4.7 ohm in series C94 for lower EMI
If no strict requirement on light load efficiency, reduce R44 and R118 10X times smaller…
Part Number: LMR36006-Q1 Other Parts Discussed in Thread: LM46000-Q1 , LMR36006 Hi,
I am working on a design to covert 12/24V DC battery to 6~7V, then through a LDO to 5V to power a MCU. I find out that both LMR36006-Q1 and LM46000-Q1 meet the requirement…
Part Number: LM46000-Q1 Other Parts Discussed in Thread: LM46000PWPEVM ,
1. We are trying to meet RE102 Ground emissions spec with a LM46000-Q1 switching regulator. Noticed a blank part location between SW and GND on the LM46000PWPEVM evaluation board…
Part Number: LM46000-Q1 Hi,
I got a problem with the simple switcher LM46000-Q1. When I apply the target input voltage on the Vin pin in one step (0V->24V) the LM46000-Q1 does not work properly. The output voltage reaches only 2V-3V instead of 12V.…
