Part Number: TPS628501-Q1 Other Parts Discussed in Thread: TPS62811-Q1 Hi Expert,
I am selecting 5V to 3.3V buck, and get confused by TPS628501-q1 and TPS62811-Q1. Could you please tell me the difference between them? Also, how much does the output voltage…
Part Number: TPS62811-Q1 Hi team,
VIN=5V, Vout=1.0V, Fsw=2.25MHz(internal OSC), SSCG=ON
Given min-on-time (max) = 75ns, maximum frequency at above condition is calculated as 2.67MHz.
But the maximum possible frequency violate this 2.67MHz as below.
Fsw…
Part Number: TPS62811-Q1 First, there is a bug in the spice model for this device.
If you look at the .lib file for this part, you used '/' characters in the pin names for the sub circuit. This really kills simulator portability and made it not…
Part Number: TPS62811-Q1 Other Parts Discussed in Thread: TPS62840 Hi Team, May we ask for more information about the ILIMNEG parameter listed in the datasheet? Does this imply that the TPS62811-Q1 has the capability to sink current from the output? Thanks…
Part Number: TPS62811-Q1 Hi team,
I would like to enable TPS62811-Q1 (Vout = 1.15V setting) into pre-biased (1.1V) load.
It looks this device has active discharge feature, but I am not sure if it (50ohm pull down) is active all the time during device…
Part Number: TPS62811-Q1 Hello Team,
My customer asked us to review their application schematic of TPS62811-Q1(Full part # : TPS628110AQWRWYRQ1, 1.2V fixed output version) as attached schematic below. Please help to review if there are something to be improved…
Part Number: TPS62811-Q1 Do you have an output impedance plot across frequencies up to the bandwidth of the regulator? For our design, we are operating at 2.2MHz.
Part Number: TPS62811-Q1 Hi team,
Vin=5V, Vout=1.8V, Iout=0.5 to 1A Fsw=2.1MHz
If I calculate inductance based on 30% inductor ripple current, the inductance should be around 1.8uH.
So I would like to use 1.8uH to 2.2uH coil for LC filter with matched…
Part Number: TPS62811-Q1 Hi team,
Could you share the bode plot to see phase margin and gain margin of TPS62811-Q1 for the following condition?
Vin=5.0V
Vout=1.8V
Fsw=2.25MHz
Compensation mode : 1, 2, 3
Load current : 1A
I would try webench, but it seems…
