Part Number: LM3151 Hi,
To calculate the soft start time following the formula in the datasheet, the typical Iss value is 7.7 uA in the design example, but in the Electrical characteristics table it is 7.7 mA. Which one is the correct?
Best regards…

Hi all,
I built a board directly based on a webench design that is attached. When I plug in my power source (LiPo battery pack) I get nothing on the output. The IC is seated correctly on the PCB and I measure ~5…
Guru,
In that case your best bet would be LM3151, LM3152, or LM3153.
1. Input voltage range 6-42V, 6-33V, 6-42V
2. Output voltage : 3.3V
3. Output current : up to 12A
4. Internal pull- up on EN pin
That's the closest we've got for your specs…
Other Parts Discussed in Thread: LM5118 , LM3151 , TPS56121 Hi, We used LM5118 in order to provide power supply for an embedded board. The LM5118 is designed to provide Vout = 10 to 15V - 4A : Vin = 10 to 30V We adjust Vout with Rfb1 and Rfb2 with a numeric…
Other Parts Discussed in Thread: LM3150 , COT Hi,
I'd like to ask about the need of external ripple injection circuit for LM3150.
According to the attached PDF file page 14,
It saids that we need the external ripple injection circuit when the output…
Hi Lowe,
Please can you share with us your design schematic? Also, by 'shifting' of loads, do you mean controlled transients or random steps?
The datasheet 'Design Guide' section gives a good description on calculating the compensation, also I've…
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
