Hello Chris,
Thanks for posting to the sensing forum!
Our ultrasonic devices are geared towards time of flight applications, used to transmit the ultrasonic pulses, receive the ultrasonic echo, and condition the returned signal to extract the ToF of the…
Part Number: ADS1212 Hi,
My customer need assistance.
Wiring as follows: AinP connected to analog voltage input; AinN to grounding; AGnd is connected to analog ground; Vbias is floating; CS connected to MCU; DSYNC connected to + 5V; Xin input 2MHz active…
Part Number: TPS62912 Hi TI Support,
We recently fabricated 10 boards using a new design with TPS62912. The build is experiencing a high failure rate. The design came off Webench. See specs below.
We saw 4 boards with output high (40% failure which…
Hello Caliber,
The main issue with high frequencies is that they cause the device to dissipate more power and heat up. And extremely rough calculation is that:
P = Fsw * VDD * Qg
This power multiplied by the junction to ambient thermal resistance gives…
Part Number: LM61440-Q1 Other Parts Discussed in Thread: LM61440 I'm trying to create BUCK regulator using TI LM61440 with the next input
Input voltage 9 -16V
Case 1:
output : 5V@2A
At 2MHz switching frequency it works
When I'm trying to reduce the…
Part Number: TPS61378-Q1 Hello Team,
My customer is trying to calculate compensation for the tps61378 and had a question about the internal feedback resistors on Spielberg.
For the fixed 5V output, what should we use in the quickstart calculator as Rup…
Hi Gareth,
Please use the LM25141-Q1 quickstart calculator to check your design. Here are some comments on the schematic:
4.7uH seems a bit high for a 2MHz design (check recommended value in the quickstart file based on the 15mOhm shunt).
Set LOL gate…
hi Zack,
Customer uses TPS61178 EVM and change the IC to TPS611781.
also change the Vout to 5V and fsw to 2MHz. they just follow it as simulation schematic.
The same issue happens on their board.
BR,

Part Number: LMR61428 I'm an old-school developer with mostly linear-regulator experience and am looking for tips on picking the right 'boost' switching regulator for a specific project. It needs to take +5V in, either from a wall-wart or a battery, and…
