Hi Steven,
After conferring with the team the C834 capacitor may be interfering with the SW node waveform. Please test this design without the C834 and see what this does to the SW node waveform.
If this does not work the problem may be that the device…
So can I assume that the LM22672-Q1 is better than the LM22672 (industrial grade) in terms of ESD (CDM) ? If I use LM22672-Q1 instead of LM22672 ( industrial grade) in product, can improve the reliability of product?
Part Number: LM22672 I have an RMA board with a malfunctioning LM22672. I'm conducting tests on the 5V circuit by disconnecting R165 and R166. The circuit is powered by 30V at 200mA. Upon powering it on, the power supply indicates 93mA power consumption…

Please find attached schematics.
Vin = 10V to 30V
Vout = 5V
Iout = 50mA to 100m
During 5V turn-on high inrush is observed. I am using a 1uF capacitor on the SS pin which is the…

Hi teams:
VIN=24V; Load: no load;
1. First ground the EN pin of the chip (remove r215), and then test the power consumption of the whole machine at 5.4ma. Then I cut off the VIN pin of the chip, and then test the power consumption…
Part Number: LM22672 Hi,
My customer need assistance.
Waveform of SW pin is not a square wave. Is it normal? Please check attached waveform and schematic.
Please help. Thanks.
Part Number: LM22672 Dear team,
I want to confirm if LM22672 could work at DCM mode? If yes, how about the effect work at DCM mode and CCM mode?
Thanks.
Best regards,
Sammi
Part Number: LM22672 Tool/software: WEBENCH® Design Tools I’m planning on using the LM22672-ADJ but can’t seem to get this modeled in Web Bench. I’m planning on using this part at 12Vout with a Vin = 18V to 36V. Web Bench is trying to…
Hi, R201 was never used in that design, its from a former design with LM22672 and builds a voltage divider for the EN Pin, instead of C205 a resistor to GND was placed.
