Part Number: TPS53319 Hi,
TPS53319 is being used to generate 3V3 from 18V on our custom board (the schematics screenshot is attached). The product is failing in CISPR32 Class B radiated emission test (at 3m distance) in 35MHz to 46MHz range. On probing…
Part Number: TPS53319 Hello,
My customer is using the TPS53319DQPR with VIN=12V and VOUT=0.882V or 1.177V.
They have some questions about the device.
Q1) Is there a shutdown function according to input voltage changes? If so, what V is the input voltage…
Part Number: TPS53319 Hi TI expert,
We have an interesting question from your file ( SLUA851A, on page5, Figure 4), and there is a reference circuit taking about minimizing switch ringing by adding RC snubber.
However, the RC snubber was connected by CR…

Hello,
My application is converting voltage from two lithium ion batteries (roughly 5~9 V) to 1.2V, 3.3V and 5.0V. I've got three TPS53319 controllers to do the job.
I'm testing the 1.2V one, but it gives zero output. The only…
Part Number: TPS53319 Planned application: 20V from USB-PD stepped down to 5V using TPS53319. Schematic etc hasn't been started yet but will be once the final IC is selected.
Looking for preconfigured parameters for outputting 5V I stumbled across…

Part Number: TPS53319 Hi support team.
I received a inquiry from my customer.
Is it permissible to apply voltage from an external circuit to the VREG pin when VDD=0V?
A voltage (3.3V) is applied to the VREG pin before the device starts up (VDD=0V).
Is…
