Part Number: TPA3250 Dear All
we have made a amplifier based on TPA3250
PVDD is 36V, Load is 4ohm, out put is coming 125W; PVDD capacitor is 2200MFD/63V
We are facing one issue
when we switch on the amplifier ..it is giving a loud sound " Thuk",,…
Part Number: TPA3250 Hello team.
We are using TPA3250 Class D IC for our application, during the testing we have noticed the CLIP INDICATION is a PWM signal.
As the output voltage we increase the the PWM of the CLIP is starting to reduce its duty cycle…
Part Number: TPA3250 Hello team,
We have designed the TPA3250 Board for power amplifier application.
During power up cycle, when turning on 24V supply will be given instantaneously to TPA3250 and we want isolate and test the 12V rail which is coming…
Part Number: TPA3250 We are using TPA3250 Class D IC in our design for 120W application in PBTL mode with 4 Ohm load.
We are using 36V supply voltage in our design for Class D IC but in datasheet we have seen maximum PVDD is 38V. Whether it will cause…
Part Number: TPA3250 Hello Team,
We are currently working on 60W amplification circuit designed using TPA3250
During the testing we can see that Fault pin toggle for short duration to low level(0V). Could you please suggest what might be the reason for…
Part Number: TPA3250 Other Parts Discussed in Thread: TPA3255 Hello team,
We are currently using TPA3250 and TPA3255 in PBTL mode.
We have a transformer connected to the output for stepping up the output signal.
Could you please clarify whether the DC…
Part Number: TPA3250 Could you please help with below queries:
1.The TPA3250 has some short detection and protection of the outputs to ground. How does this work in combination with the 470uF in series? With the 470uF in series, DC on the output can be…
Part Number: TPA3250 Hi we are using TPA3250 in PBTL mode
using this for audio power amplifier ( from 30Hz to 18Khz) response, running at 35VDC.
amp is working fine with THD 1%, output level 125W, at 4ohm speaker load.
amplifier is used to make a audio…
Part Number: TPA3250 Hello,
in the design of TPA3250, the fault pin is triggered to low since the AVDD is dropped off from 7.8V to 6V every 220ms.
A 1uF capacitor is used for this pin. The loudspeaker is not connected.
Beside, the CLIP_OTW is always high…
Part Number: TPA3250 Hi we are using TPA3250 in PBTL mode
using this for audio power amplifier (woofer low frequency application)
running at 35VDC,
Query is when we are running at 100 hz input signal ,,,out put is coming 100W only at 1% THD clean sine…
