Part Number: TPS62175 Dear support-team!
According the datasheet of TPS62175 the soft-start mechanism rises the output voltage with a typical rise time of 10 mV/us.
Is there the possibility to calculate/determine the worst-case rise time during startup…
Part Number: TPS62175 Dear support team!
In our application we use the TPS62175 with a very low output current (120mA) and therefore in DCM -> the device should then remain in power save mode.
According datasheet the device shall then use the minimum…
Part Number: TPS62175 We are working to minimize power consumption in our battery-powered product. We observed the unexpected behavior that the TPS62175 is consuming slightly more current in SLEEP mode than in normal mode. We'd like to verify that we're…
Part Number: TPS62175 Dear Sir,
I use TPS62175 to desing a 12Vin to 3.3V/0.5A DC-DC Converter.
Initial I found switching frequency can't up to 1MHz(arround 820KHz) during Io=300mA.
I modify layout change VOS loop from near inductance to output cap…
Other Parts Discussed in Thread: TPS62175 Hi,
I use TPS62175DQCR converting 24V DC to 5V DC to power the RS-485 signal chain block with reference to TIDM-1005 REV E1. It doesn't work. I measured voltages at different pins. The voltages at pins of VIN and…
Part Number: TPS62175 Dear Sir,
My customer use TPS62175, Switching frequency is abnormal during Vin=12V Vo=3.3V/500A
In scope show switching frequency is 500KHz(not 1MHz).
Please you kindly review circuit/ waveform & provide suggestion.
Thanks!

Part Number: TPS62175 Hi,
When I tie "Sleep" pin on TPS62175DQC ICs to GND, I do expect to see a drop in current delivery to the output, but my circuit is still capable of providing 500+ mA regardless of the state of SLEEP pin.
I can measure…
Part Number: TPS62175 Hi TI support,
=> We are facing startup issues with TPS62175 design. It worked well till now with 0.25A resistive load.
=> But as same design could be used upto 0.5A, I tried using it for 360mA load & found Vout is stuck at 2…
