Part Number: TPS62933 Tool/software: Hi TI-team, I am using a TPS62933O to power up an Attiny and other PCB-Logic. I noticed a high input current (aprox. 5 mA) even if there is no load connected to the output. I looked at the SW-Pin (yellow) an Vout (blue…
Part Number: TPS62933 Using the reference circuit on the datasheet, I was able to get 5V output voltage on the first power up. However, after the second power up, I could no longer get 5V output voltage.The input voltage is the correct 8 V. I also checked…
Part Number: TPS62933 Hi TI Specialist:
I have some queries for TPS62933 converter during try to create a new simulation file for testing, but i couldn't find the key parameters from the datasheet on website, please help to check and advise, thanks…
Part Number: TPS62933 Other Parts Discussed in Thread: INA180
Hi, I'm adding the INA180 op amp at the buck output. Vout is stable 12V, 500kHz. The current sensor equation is: Iout * 10mOhm * 100V/V = Vadc
For example, when Iout = 1A, nominal current…

Part Number: TPS62933 Other Parts Discussed in Thread: INA180
I am utilizing the INA180 for monitoring DCDC current. The INA180 amplifies the voltage across the current sensing resistor, presenting a sine wave pattern as observed on the oscilloscope.…
Part Number: TPS62933
Hello team,
My customer wants to use this device in condition below:
VIN: 24V
VOUT: 12V
IOUT: 0.5A
FSW: 500kHz
However, customer wants to use inductor of 10uH, which will result inductor ripple current to be 200% of IOUT. Datasheet…
Part Number: TPS62933 Hi, when TPS62933 has no load (Iout=0A), the SW signal has oscillations. Is this normal?
When there is a load (Iout>0A), the SW signal is nice clean PWM/square wave.
