Part Number: LM20333 Other Parts Discussed in Thread: PSPICE-FOR-TI , TLVM13630 Tool/software: Hello: I am trying to perform transient simulation of a switching power supply using the LM20333. The available model is for TINA SPICE, so that is what I am…
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…
Part Number: LM20333 I am using a DC-DC converter IC LM20333MH in my product design. I had built 4 boards during Feb and all those 4 boards are working without any issues. There was no problem for the power supply bring-up as well.
I got built 2 more…
Part Number: LM20333 Dear, Sir.
My customer is lokking for the device to protect against the abnormal FB volatge
due to resistor divider open or short.
LM20333 has the undervolage comparator inside on FB path.
Could you please explain the behavior…
Part Number: LM20333 Dear, Sir.
My customer is looking for the device to protect against abnormal FB voltage due to
external FB resistor divider open or short.
LM20333 looks have the internal undervoltage comparator inside of FB path.
Could you…
Part Number: LM20333 Dear, All
Customers are considering using LM 20333. They want to make the output voltage variable, and are considering using the SS/TRK pin. They do not want to enter discontinuous mode because they want to make the output voltage…
Other Parts Discussed in Thread: LM20333 Hello, I have problem with LM20333 DC-DC. At light loads, it starts oscillating. When load is applied, it starts work well. When load step is applied 1A -> 0A, thjere is 50% chance, it will start oscillating or…
Other Parts Discussed in Thread: LM20333 , LM5022 Hello,
I was wondering if anyone has used the LM20333 in a flybuck configuration. I need the following:
- synchronize to a wide range of switching frequencies (500kHz or lower up to 1MHz)
- 6.5-7V…
Other Parts Discussed in Thread: LM20333 I have a question regarding synchronization of the LM20333 to an external clock source. I believe that I have a design that essentially works but there is jitter in the switch node waveform with respect to my external…
Hello,
Please tell me how the current limit functions.
In the datasheets, it is merely mentioned that some reference voltage decrement and resulting foldback will occur (shown below).
I want some more detail, because it is a critical informatin…
