Part Number: TPS65137AS Tool/software: Hi Sir ：
We have found an issue with TPS65137ASDSCR regarding this chip, which is that when unloaded, the output positive and negative voltages are correct, but when connected to a screen load, both positive…
Part Number: TPS65137AS Dear Experts,
We are using TPS65137AS to provide power to a 1.9" AMOLED display based on RM67162.
Here is a schematic:
And the PCB layout:
If the display is not connected then everything seems to be fine (CH1 - OUTP…
Part Number: TPS65137AS Hello Expert,
I want to clarify to set change of negative voltage and ask about TPS65137AEVM-366.
When I understand and check the data sheet like below waveform.
The sequence is first enable (CTRL first High) and then default…
Dears,
please could you provide an efficient procedure to test PSSR on TPS65137A ?
how can PSSR be evaluated on full input voltage range / frequency ?
thanks and regards
Hi Mikkel,
Thank you for your interest in the TPS65137A & TPS65137AS.
Could you let me know what application you're working on & where TPS65137A/AS could fit, in case I can help you identify a more suitable device, especially given the AMOLED market…
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,
