Other Parts Discussed in Thread: TPS63030 Hello, We have a board using the TPS63030 set to output at 5V. The design exactly follows the datasheet with a 4.7uH inductor, 4.7uF on the input and 10uF on the output. It is not in low power mode.
Quite often…
Hi,
I believe that the feedback voltage(VFB) value of datasheet is the “495mV(min) / 500mV(typ) / 505mV(max)” at PS/SYNC=VIN , TA=25℃.
However, my customer would like to know the VFB value at PS/SYNC=VIN , TA= -40℃ to 85℃.
Please let me know this…
Other Parts Discussed in Thread: TPS63030 What happens if the TPS63030 is enabled when there is an existing pre bias at the output?
i.e. my Vout is set to 3.3 V, but prior to turning on the part, there is already a 3.8V pre bias at the output.
Other Parts Discussed in Thread: TPS43000 , TPS63030 , TPS22946 I'm consdiering a TPS63030 , and I'm considering trying to limit its current to 20mA. Is there any app note for limiting the output current?
Thanks,
CJ
Other Parts Discussed in Thread: TPS63030 Will the TPS63030 support a Vout = 2.5V with a Vin = 2.7V @ 100 mA? I ran this through SwticherPro and it generated a schematic, but the efficiency curves are very suspect and do not look correct.
How much ripple should I expect in PS mode?
In the thread at this link , a user says the datasheet shows 100mV ripple in PS mode. I do not see this in the datasheet.
I am seeing 100mV. I have been experimenting with my board. When I had 10uF output…
Charles,
I experimented with the TPS63030 EVM this morning. Testing shows the part can handle prebias voltages above and below the Vout setpoint. There is no voltage undershoot when the part responds to a prebias > Vout.
Test 1 setup:
Vout =…
Yes, the Power Save Mode will not allow the the device to sink current. If you force PWM, disable the power save mode, then the device will sink current through the low side FET and the output FET. This current is unknown and could be a cause of damage…
If the output of your battery pack is the 3.3V output of our regulator, you cannot use that same connection to charge your battery. The TPS63030 converts power in one direction--from your battery to the 3.3V. It is not designed to convert power from its…
Other Parts Discussed in Thread: TPS63030 , TPS61220 Hi!
Attached you can find the circuit around the TPS63030. Its output voltage is configured at 3.0V. When the device is put in sleep mode, the output current drawn from the regulator is 30uA @ 3…
