Part Number: LM22672 I'm using LM22672 fixed 5V output for my design.
12V input.
Supplying 5V on the board separately, the load is about 0.5-0.8A. However when using the LM22672 the switcher gets to hot. About 100degree Celsius.
Do I need a different…
Part Number: LM22672 We are using LM22672 in a buck / inverter circuit stepping down from +24 V to ±16.8 V. We are seeing an issue on multiple boards where the switch node isn't going all the way to ground:
On a good board it does:
When this happens…
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…

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 Merry Chrismas!
Can you please help me with the ESD (CDM) withstand voltage rating of the LM22672MRX-ADJ?
I am currently unable to access the exact information from TI's datasheet as well as the reliability documentation.
If…
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,

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…
This is for a Housekeeping supply for a larger 650W isolated DC-DC converter. This Housekeeping supply provides 12V for driving the MOSFETs and running some other ICs. The expected current will likely be ~200mA or so, but I want to use the LM22672-ADJ…
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.
