Hi Marvin,
I'm not sure about detailed requirement of your specific application. There's VID function for TPS51513 and integrated 2A LDO output for TPS51511, which aren't included in TPS51219.
For more similar devices with TPS51219, I would…
Minglai,
Generally what you propose is not a constant current source, since your output voltage is fixed at 3.3 V. For constant current source, the output voltage will change according to the load to keep the current constant. In your case, you will…
Chen,
I think TPS51117 or TPS53219A are the closest matches. TPS53819 may work also, but it has BMBus, which you probably do not need. APW8828 OCSET is not a current monitor pin. It is a pin to set the current limit. Both TPS51117 and TPS53219A have…
Hi Patrick,
I think you should talk about TPS51220A, not 651220A.
If you want look into single contoller, you can check TPS51117/217... series

Other Parts Discussed in Thread: TPS51117 I am using TPS51117 for notebook GPU power, but our customer concern the ringing at switch node at light load.
How could I reduce the ringing at switch node and explain it?
Thanks
Other Parts Discussed in Thread: TPS51117 , TPS51116 I read some datasheet of synchronous buck controllers. Most of them show the parameter: sink current and source current(I know what they are). Yesterday I read the datasheet of TI TPS51117, it has another…
