Part Number: TPS65235 Other Parts Discussed in Thread: TPS65233 Dear SIr
May I know
1. TPS65235-1 have a better price than TPS65233 ,if the R/R is the same
2. How about the TPS65235-1 surge test result ?? if we need pass surge +/- 4KV ,does TI have any…
Part Number: TPS65233 Background: We are having an issue with our products SW when controlling TPS65233 over I2C. Root cause is in the software that we currently cannot prevent it reading 0x2 register from the LNB controller. By unfortunate coincidence…
Part Number: TPS65233-1 I would like to power the TPS65233-1 with 6 V. Should I connect the 6 V to VIN and VCC, just VIN, or something else? The data sheet says VCC is an internal 6.5 V power supply, and that when VIN is 5 V, connect VCC to VIN. So I'm…
Part Number: TPS65235-1 Other Parts Discussed in Thread: TPS65233 Hi, Team,
Absolute Min spec of VIN, LX, BOOST, VLNB are 1. Is this description error?
Best Regards, Satoshi Yone
Part Number: TPS65233 Dears:
When system Power ON, the position of the tone on the output voltage is in the middle of Vout as described in datasheet.
When we switch to the low local frequency point to stop 22K signal, and then switch back to the high…
Hi, Karo
1. If want to use I2C to control TPS65233, you shoud set bit7=1 in control 1 register, then EN/ADDR pin is just used for addressing.
2. Yes, if set bit3=0, the VLNB will be pulled to GND.
Hi,
TPS65235 is a new part, compare with TPS65233, it has different package, Fsw support 1MhZ, support DiseqC2.x.
1. Yes, it has almost same switching loss under same Fsw.
2. No, it has different pakage and pin out.
3. What is the meaning of coil? different…
Part Number: TPS65233 Page 3 of the datasheet shows the Typical Application.
There are no values shown in the Typical Application picture for the following components:
Capacitor connected from pin 14 to pin 15.
Schottky diode connected from pin 15 to…
Hi, Sir
The waveforms is abnormal.
I have checked the schematic, some components value is not right.
1. Change C1446 to 22nF.
2. Change R1423 to 130kohm.
3. Change C1441 to 1uF.
Please refer schematic and BOM in the page11 & 12 of TPS65233 EVM user…
