Hi Helen
The VREF reference voltage is already available at startup, without any problem.
For some reason, when the short-circuit happens and I try to recycle the TL331 the current is not cut and it increases a lot. I expected to disconnect I don't understand…
Dear Sir,
You need to add a disconnect MOSFET(or load switch) at the output side. You can refer to the TI design PMP9779 for a reference.
So you can also choose a TI part with load disconnect function, like TPS61022.
Part Number: TPS61088 Other Parts Discussed in Thread: PMP9779 , TPS61178 When EN pin is pulled low, TPS61088 is in shutdown mode. But Vout is not down to 0V. I understand this is a specification of TPS61088.
Is there any way to be down Vout to 0V?
Regards…
Dear Sir,
As TPS55340 doesn't has short circuit function, so extra component must be added. Please refer to the TI design PMP9779. The concept will be similar.
Part Number: PMP4451 Other Parts Discussed in Thread: PMP9779 Tool/software: Code Composer Studio Dear Sir,
Can I put a short circuit such as PMP9779 circuit?
How do I download the source code?
This specialty is provided at High School.
Ihope to near you…
Other Parts Discussed in Thread: PMP9779 Hi, Could you tell me about disconnection between Vin and Vout circuit example? I read the following post. https://e2e.ti.com/support/power_management/non-isolated_dcdc/f/196/t/439877
Customers want to cut off the…
Other Parts Discussed in Thread: TPS61089 , PMP9779 , TPS61178 I am in search for a boost converter that will do following:
Vin = 5V ~ 5.3V
Vout = 6V
Iout = 2A min , the load will pull 1.8A
built in switch
load disconnect when disabled
low quiescent cur…
