Part Number: TPS65130 Other Parts Discussed in Thread: TPS65120 Hello ,
In the debugging TPS65130 , we found that the VSP(positive voltage) has a drop during start up .
we try to remove C12 and increase C12 to 12pf , this drop cannot be eliminated…
Hi Roy,
The only multiple positive output SIMO switching regulator that I am finding is TPS65120/21/23/24 device that have two positive outputs and a negative VGL output for biasing a source and gate supplies of an LCD display. Datasheet is available…
Other Parts Discussed in Thread: TPS65120 In the datasheet on page 16 is mentioned:
All TPS6512x outputs are protected against a short circuit to ground. During steady-state operation, if the output
V MAIN , V GH or V GL falls below its fault detection…
Hello James,
Possible other recommendations are dependent on the input voltage range, the needed output voltages and the maximum output current. An idea could be TPS6512x family of devices: https://www.ti.com/product/TPS65120
Or TPS65135 although…
Other Parts Discussed in Thread: TPS65100 , TPS65120 , TPS65101 Hello,
I have a question on TPS65100.
In an application I need 4 power sources,
1)VGL at -6.8 volts
2)VGH at +20 volts
3)VCOM at +3.46 volts ?
4)VDDA at +11 volts
I am thinking…
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.
