Part Number: TPS62812-Q1 The TPS62812 has Optional Spread Spectrum Clocking function, but in page3 5 Device Comparison Table, all FEATURES spread spectrum clocking is OFF.
When the device is externally synchronized by applying a clock signal to the…
Part Number: TPS62812-Q1 Hi,
In datasheet, the maximum inductor (assuming Fsw = 2.25MHz) is 0.9uH. Can one increase inductor value higher than 0.9uH for reduced current ripple? Will this cause any potential instability?
Thanks.
Part Number: TPS62812-Q1 Hello Team,
I got a question about frequency variability.
When COMP/FSET connected VIN or GND directly, the Fsw variability is +/-10%. When using using a resistor, the Fsw variability is 18%!
Why does the variability get…
Part Number: TPS62812-Q1 We are interested in operating this chip in SSC mode. We would like to get more data about this - i.e. how does the noise power spectrum look like when we operate the feature vs. "normal operation,
how is the spread spectrum…
Part Number: TPS62812-Q1 Hi TI-team
It may be a basic question, what do you mean that "duty cycle of synchronization signal at MODE/SYNC Pin"
Does it mean that it accepts and operates when the duty of the external CLK is between 20% and 80%…

Hi JH,
Thanks for reaching out to us.
I recommend TPS628502-Q1 if SOT-563 package is fine with customer. If not, TPS62812-Q1 (QFN package) is alternative choice as well. TPS628502-Q1 is a cost-competitive compared to TPS62812-Q1 due to higher Rdson…
Hi Pratik,
Can I ask why you need this data? The transfer of the heat is actually towards pins not to the bottom. For an estimation, you can use junction to case (top) thermal resistance.
