Part Number: TPS40195 Hello,
I use this integrated for a 12V to 5V converter.
Problems encountered:
At pin 16 (HDRV) I have a constant voltage of 3V
At pin 14 (LDRV) I have a constant voltage of 4.4V
And the output voltage is not 5V, it is 3V.
At pin…
Part Number: TPS40195 Other Parts Discussed in Thread: LM25117 , LM5141 Hi Team,
I would like to find the solution which could meet below requirements.
1. Vin = 12V
2. Vout = 10.5V-8V
3. Iout = 10A
And I found that duty(max) is 87.5%. It couldn't meet…
Other Parts Discussed in Thread: TPS40195 Hi ,
we are using the TPS40195 with RT Resistor set for 0.8 x 600Khz and a SYNC signal of 600Khz without problems.
But now i need to answer the question what happens if the clock signal connected to SYNC is corrupt…

Other Parts Discussed in Thread: TPS40195 Hello,
I would like to know about absolute maximum rating of LDRV pin.
LDRV pin ratings is "-0.3 to 6V"
But I can see the negative spike about -0.8V in the figure 18 at the datasheet page 14.
Is this device…

Other Parts Discussed in Thread: SWITCHERPRO , TPS40195 Hi,
where is the right position for R4?
In Tina TI an The User Guide for the TPS40195EVM R4 is parallel to CBoost:
In datasheet R4 is serial to CBoost:
What's right?
