Part Number: TPS63030 Tool/software:
Hi,
In a project where we use TPS63030, we want VOUT=3.3V but we get VOUT=0.8V output.
VIN = BAT-VF = 3.330V VEN=3.330V VOUT=0.803V VFB=0.499V
We couldn't understand where the problem is. How does VFB become…
Part Number: TPS63030 Other Parts Discussed in Thread: TPS63060 Tool/software: I am trying to driver a laser diode using the TPS63060. I have a variable power source from 3-6VDC (Vin). The laser diode has a Vforward of 2.5V. During power up the circuit…
Part Number: TPS63030 Tool/software: Hi team,
Our power circuit has TPS63030. Fig 1 is overview of our circuit and Fig 2 is waveform at start up.
We would like to ask about that, TSP63030 is shutdowns at T7 to T9 by its UVLO function, but about 5V…
Part Number: TPS63030 Other Parts Discussed in Thread: TPS631010 , TPS631000 Tool/software: We need an alternative buck-boost converter IC with the same pinout and footprint but better output current, upto 1.5A supporting IC. Please suggest us options…
Part Number: TPS63030 Tool/software: Hello, We're seeing MCU (STM32L151RET6) resets and traced it back to 1.8V rail dropouts happening on the TPS63030DSKR output. It appears that this may be happening during the transition out of PS mode (see images)…
Part Number: TPS63030 Hello,
I am using the TPS63030DSKR component to boost from 4.9V to 5.25V, with output current 3mA-40mA depending on the load. I followed the reference design for both schematic & layout, as of this moment I can hear ringing tones…
Part Number: TPS63030 Hi guy i have some question on this device TPS63030DSKR i do the 2 typical designgive in the datasheet but i dont have the 3.3V in aouting i use for R1 R2 this 2 value 840K and 150K i can have some help please ?
Hi,
the layout is not good.
please rotate the C6 and C7 180 degree, so the routing between the IC ground and output capacitor capacitor ground is minimized.
you can do this experience in the current board, then replace the IC to a new one and test…
Part Number: TPS63030 Hello, We are using a TPS63030 adjustable regulator with feedback resistors for a VOUT of 3.3V We have 3 x AA (1.5V) cells connected to VIN through a diode. We also have VBUS (from a USB connector) connected to VIN through another…
Part Number: TPS63030 Hi,
We power an ESP32 with a TPS63030 using 2x C type alkaline batteries in series.
To allow the batteries to fully drain and to avoid brownout we use a 2000uF capacitor on the output of the buck-boost (3.3v).
When powering…
