Part Number: TPS43330-Q1 Hello Team, We are using TPS43330 Buck-Boost IC in one of our designs.
For 1 buck, which we have set to 4.1V, the output voltage is not generated and switching waveforms also look incorrect.
We have changed the IC and External…
Part Number: TPS43330-Q1 Hello Team,
We are using TPS43330-Q1 in one of our designs. The Buck B section is set to 3.5V. We are observing strange behavior with respect to Buck 2 output. Sometimes output voltage is setting to 3.5V and sometimes the voltage…
Part Number: TPS43330-Q1 This thread applies to TPS43330-Q1.
In device TPS43330 (non-A version): When device in LPM and waking up EXTSUP gets shorted to VREG and that may cause a restart of the device (including running buck regulators): High-IQ in…
Part Number: TPS43330A-Q1 Other Parts Discussed in Thread: TPS43330-Q1 , , TPS54618-Q1 , TPS54618 Hi Team,
What is the primary difference between the "A" & "non-A" versions of this device? Understood that the non-A is considered NRND today, but my customer…
Part Number: TPS43330-Q1 Other Parts Discussed in Thread: TPS43330A-Q1 Hi,
We are checking the feasibility to use TPS43330 in one of our requirements. Regarding this IC , I have below query. Could you please provide the below info at the earliest?

Hello Perry,
I believe the 300mV output ripple is at light load and when the ripple is lower when load is connected. This is due to pulse-skip at light load. The output voltage ripple at light load depends on the inductor peak current. It will be lower…
