Part Number: TPS61071-Q1 Hi
I have three questions about TPS61091-Q1.
1.
The VFB is typ 500mV(±10mV) at Ta=25℃ in datasheet.
Could you tell me the VFB over temperature?
2.
Is the L1 of equation (3) and (4) the maximum average inductor current…
Part Number: TPS61071-Q1 Tool/software: WEBENCH® Design Tools Hi
I simulated TPS61071-Q1 under Vin=3.3V, Vout=5V, Iout=200mA by Webench.
But I couldn't simularted it because switch current limited exceeded.
I think this device can operate that condition…
Part Number: TPS61071-Q1 Hello,
for EMC reasons we want to use a 22µH inductor instead of the recommended 10µH.
The data sheet says the optimal range is up to 10µH, but higher values can also work and stability should be evaluated.
…
Yichen,
For the first revision of the design, the smaller inductor will be populated and tested. If there are issues with audible noise then the larger 4.2 mm x 4.2 mm inductor will be tried. If audible noise is still present then we'll look at using…
