Part Number: TPS55287 I am testing a board with a TPS55287 switch regulator. At no load I expeted a single switch puls and then a pause in PFM operation. What I get is three pulses (at the selected swtich frequency) and then a pause. When the load increses…
Part Number: TPS55287 We are evaluating an unmodified TPS55287Q1EVM, except that CDC is connected to an STM32G071 ADC through 1 kR series resistance with 100 nF to ground.
The EVM has a 20 mR shunt and nominal CDC gain of 20 V/V, giving 0.4 V/A.
Measurements…

Part Number: TPS55287-Q1 Other Parts Discussed in Thread: TPS55287 , TPS552872 Hi,
I am looking to add a 2nd power input to an existing design which uses the PD controller to negoiate 5-20V Sink. The TPS55287-Q1 looks to be a suitable part (for buck…
Part Number: TPS55287 Tool/software: Hi
I tried to communicate TPS55287 via I2C(Baud rate 500Kbps) but look like getting NACK signal after sending the address(0x74).
You can see the below screenshot for I2C waveform.
