Part Number: LM3674 Tool/software: Hi team,
At startup, -0.6V is observed, exceeding the absolute maximum rating of GND-0.2V. However, looking at Figure 17 in the datasheet, it seems that the voltage exceeds GND-0.2V at startup as well. Can this device…
Part Number: LM3674 Other Parts Discussed in Thread: LM3671 , LM3670 Dear team,
the device is used in multiple designs and so far the -30°C was OK. There is a new request for going down to -40°C. Ideal the customer could reuse an existing design and…
Part Number: LM3674 Hi Team,
Greetings! We need your assistance for the customer's inquiry below.
We are using LM3674 -adj version of the device in our design to generates 1.2V from 3.3V power supply. We have 280K and 200K as standard Feedback Resistors…
Other Parts Discussed in Thread: LM3674 Hi all,
I'm designing a remote control that is using nRF24L01+ as RF module (2.4GHz ISM band) and use the LM3674 as DC/DC from 3.7V 850mA/h li-on battery to 2.5V DC.
The problem is the remote control could send…

Team,
The LM3670MF-3.3/NOPB shows a Vout 3.3V fluctuation of +/-20mV at Vin: 5V, Iout=70mA. However for this application it…
Hi Villegas
Thanks for your response! Another two questions need to check with u. Thanks!
1. TUSB8020B EVM adotes LDO LM3674 for 1.1 power rail. Is it a must to use LDO for a dc-dc also ok?
2.Do we have USB3.1 GEN2 HUB device on roadmap?
regards…
Dear Brian,
Thank you for your previous guidance regarding the USB 3.0 hub based on the TUSB8020BPHP. I am currently using the TI TIDA-00287 2-Port USB 3.0 Hub Reference Design
As discussed, using a Type-A to Type-B adapter prevents the “Port Reset…

During testing TUSB8020B HUB,some issue is as below,
1. USB 2.0 peripherals access are OK.
2. USB 3.0 mass storage devices access are OK,but USB 3.0 camera acA1920-155um…
Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
Gary,
Most any of our power controllers with dual output capability will provide the control. See attached document starting at page 50 with the dual output controllers on page 53 and 54 and choose what features you want.
Regards,
John
