Part Number: LM20133 Dear Expert
We used TI's power chip LM20133 in one of our projects, which utilized the function of external input frequency synchronization (SYNC pin). We are currently encountering a problem during testing. Please help consult…
Part Number: LM20133 The damping RC circuit is already in place. But C value is same as C86 and not 5 times. PFB the 5 v generation portion which is used as input to LM20133.
The same 5 v is used to power 3 more modules which are basically relay…
Part Number: LM20133 We are using LM20133MH for generating 3.3v from 5v supply in one of our traction control module. The 3.3v is used to power one MVB protocol communication module. The power supply is intended to generate 3.3v and the operating current…
Part Number: LM20133 Hi, I am using the LM20133 switcher and, unlike many of the other similar parts, the datasheet is quite sparing in its thermal parameters. Only theta ja is listed, unless I am being really dumb. Do you have values for the characterisation…
Hello,
Is there is an internal reverse-voltage protection diode between the Vin and SW pins (connected in reverse between drain and source of the top switching FET)?
Thanks.
Part Number: LM20333 Other Parts Discussed in Thread: LM20133 , TPS54350 Hi Team,
Our customer needs a synchronous DC/DC converter with frequency synchronization from external source. The LM20133, LM20333 and TPS54350 seem fit for his application, however…
Other Parts Discussed in Thread: LM3102 , LM20133 , LMP8646 , LMP8646EB 1. Two feedback connections are shown in the document -- one in the application information (feedback is connected to Vin- on op-amp) and one in the EVB schematic itself (feedback…
