Part Number: TPS53353 Other Parts Discussed in Thread: TPS53832A Hi, My Friend:
When studying JEDEC DDR5 PIMIC spec, I found Bulk Input (VIN-BULK, 5V) of DDR5 UDIMM/SODIM is restricted as below:
1) BULK Input Ramp UP = 0.1 ~ 3.0 V/mS
2) BULK Input Ramp…
Part Number: TPS53353 Hi all,
I wanted to ask about the output capacitors' selection criteria for this specific DC/DC converter. Thera are only two scenarios considered in the datasheet: one in which electrolytic capacitors are used, and another one in…
Part Number: TPS53353 Dear TI Team,
We are designing a new LED controller board. As per requirement, board should support 5V to 12V power input. But most of the LED strips will work in 5V.
We can use a buck converter to get 5V from higher voltages. But…
Part Number: TPS53353 Dear Teams,
The output current is about 15A, so I'm thinking of setting the overcurrent detection threshold to 20A or higher. Should I calculate the threshold with Rds(on) = 1.6 to 1.7mΩ as described in the datasheet?
Part Number: TPS53353 Other Parts Discussed in Thread: TPS53319 Hi team,
customer use TPS53353 to replace original 53319, they change TRIP to 57.6kohm ( not shown in the schematic)
but there's no Vout, would you help check if there's anything we miss…
Part Number: TPS53353 Hi Team,
Customer is asking what's the meaning of below 1.2V/0.95V in below functional diagram? Does this mean enable_on range is 1.2~1.8V, disable_off range is 0.6~0.95V?
Part Number: TPS53353 Dear Team,
Today, I took a board and used an oscilloscope to capture the TPS53353DQPR VREG. The maximum voltage is 5.48V. The measurement point is the test point between C484 and IC pin18, which has exceeded the parts datasheet…
Part Number: TPS53353 Hi TI expert,
My customer measured startup waveform by TPS53353. please refer the attached waveform.
Mode pin = connect to VREG
Iout = 0A turn on
May I know this is a normal behavior or not?
