I have a product in production for a few years now that has shown a constant problem associated with the TPS60310 Charge pump. We have a new version about to go into production and the new version is much worse so I thought I would contact to find out…
Hi Martin,
You probably don't need anything too crazy to pull that off. I would think a simple charge pump could give enough current to drive just one LED.
You could try looking at the TPS60240 or TPS60310. There might be a better solution - if you…

Will OUT1 (2x VIN) of the TPS60300 operate without C2F and COUT2?
Applies to: TPS60301, TPS60302, TPS60303, TPS60310, TPS60311, TPS60…
The example attached is used for a boost converter, but the output current sense stage can be used on a buck topology.
Please note that the attached is only a concept. One will need to modify to suit the needs of the system and specification.
In the…
Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
Siyu,
I think the toggle flip-flop in the block diagram on page one of the spec should have let you know that the max you will get with this device is 50% duty.
Go to page 43 and 44 of the attached and select a more suitable part.
Peter,
i am enclosing the Power Management Guide for 2011. The section you will be interested in starts on page 43 and actual devices listed on page 46, With the minimum information you have given me I would expect that you will want something like…
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
