Re: FET or transistor available to switch 300mA@12V from MSP430 port (3V)
Hi Scott, Our current product line doesn't include small signal FET as 2N7002. You could use
CSD16411Q3
, but this part will be overkill for your application. Best Regards, Cui

Re: TPS2590 un-expected current faults at levels below the 275mA set threshold
The datasheet specs for the TPS2590 are valid only in the 1 to 4 Amp range Below 1A, the tolerence increases. The datasheet references this only in the specification table. I will put specific mention of this in the datasheet as you suggest. Your schematic...

Re: -7.7V to -5V at 7.4A needed
Angela, This is a non-synchronous appliction requiring an external MOSFET and Diode. With a 5V output voltage and 7.7V input voltage, which proper sizing of the components (as you would with a 7.7V to 5V non-synchronous BUCK converter) it should be...

RE: UCC3806 reference design and simulation model
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...

RE: How to adjust output PWM of UC3825
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.
